Description
The dragons call out, and the ratatoskas tell of murder. Come with us now. There is justice to be done.
Return to the magic of the Archipelago... The Poisoned King is the dazzling second book in Katherine Rundell's epic and bestselling Impossible Creatures series.
'There was Tolkien, there is Pullman and now there is Katherine Rundell' – Michael Morpurgo
When Christopher Forrester is unexpectedly woken by a miniature dragon chewing on his face, his heart leaps for joy. For months he's dreamed of returning to the Archipelago – the secret islands where all the creatures of myth still live. But he did not know it would involve a rescue mission on the back of a sphinx, or a plan to enter a dragon's lair. Nor did he imagine it would involve a girl with a flock of birds at her side, a new-hatched chick in her pocket and a ravenous hunger for justice...

⭐️⭐️⭐️⭐️⭐️
The Poisoned King by Katherine Rundell is a stunningly written adventure filled with magic, danger, and heart. The writing is lyrical and atmospheric, making it easy to get swept away in the world from the very first page.
Even without reading the first book, I was fully pulled into the story. The characters are bold, brave, and beautifully complex, and the pacing kept me hooked right through to the final chapter. Rundell has crafted a story that’s both emotional and exciting—a perfect blend for YA and teen readers alike.
As soon as I finished, I knew I had to go back and find the first book. This is definitely a series I want to own as a full collection—one I’ll revisit and recommend to anyone who loves fantasy with depth and heart.
Thank you to NetGalley for the chance to read this gem!

An incredible adventure with wonderful characters, a captivating world and high stakes. Five stars.
Thank you so much to the author, publisher and NetGalley for the opportunity to read an ARC.

I loved Impossible Creatures but I think I might love the sequel The Poisoned King even more - it’s such an incredible story of magic, friendship, loyalty, bravery and fantasy. It’s not publishing until 11th September but you should definitely get your pre-order in now - there are some amazing sprayed edge editions.
Set once again in the Archipelago, we see Christopher return once again to save the dragons but along the way he has to rescue Anya, the second in line to the throne who wants to live wild and free in the forest but is forced to live in the castle. When her grandfather, the king, is murdered and her father arrested she has to flee for her life.
It’s such a wonderful story to read, full of brilliant lines and lots to think about. I loved the characters and Anya is definitely one of the best heroines out there. The fantasy world is created really well and the mythical creatures are abundant - there are so many references to different mythologies and it shows just how much Katherine Rundell knows her stuff.

This was a fantastic sequel by Katherine Rundell. It was great to come back to some characters from the previous book whilst also meeting new characters and another area and culture of the Archipelago.
It's best to have already read Impossible Creatures, however the plot in The Poisoned King is a story in its own right so it is not imperative.
It's quickly paced with plenty of action and of course some some fantastical creatures, this will be loved by both children and adults.

The anticipation of a sequel is often more rewarding than when the book finally arrives and doesn't live up to the expectations.. Impossible Creatures was the "must-read' of 2023; a glorious trip into a fantastical world created by Katherine Rundell.
With so many plaudits, it could be easy for an author to be sidetracked from their game and talent and quickly produce a sequel that doesn't have the heart, but Katherine Rundell isn't that type of writer. The Poisoned King is quite simply excellent.
Christopher Forrester is back; this time on a mission to try and understand why dragons are dying- to save them. Back to the Archipelago he travels - time is running out.
But meanwhile other tragedies are taking place: a young princess discovers her grandfather has been poisoned and her father imprisoned for the crime- she needs to save him from death and also prove that another family member is power-hungry and will stop at nothing to gain power- even if it means killing other creatures
So when Christopher and Anya's paths cross they find they need to join resources, knowledge and skills to battle the enemy.
Joined by a sphinx, dragons and magical birds, the two embark on a race against time - battling against a myriad of challenges.
This is book two in a quintet and book three will be published next year. Comparisons have been made to Tolkien and Pullman but this is a distinctly Katherine Rundell world. Her prose is spell binding- never playing down to the readership - stretching imaginations through vocabulary and plot
This is another wonderful book for young (and old) - a gripping adventure full of magic, fantasy and Impossible Creatures and one that you can't put down until the final pages.
Undoubtedly another masterpiece in children's fiction - is it too early early to say Children's Fiction Book of 2025?
Very highly recommended
Thank you to Bloomsbury Children's Books and Netgalley fro the advance copy.

The highly anticipated follow up to The Impossible Creatures sure didn’t disappoint! I reread the first one in preparation for this and I was suitably hyped! I can’t believe how quickly it went and how absorbed I was.
It was great to be back with characters we’ve come to know and love and be introduced to new ones. With split character perspectives until our characters meet, we get to experience the world of the Archipelago with them. It was a pure joy! And we meet Anya who is an amazing character!
The chapters are also short and snappy and really adds to that extra ‘just one more chapter’ addiction which had me tearing through these pages in record time. It was so effortless and fun to read, I had no problem getting through this book in just a few days. I was hooked to say the least!
The central plot itself was compelling and together with Anya, we unravel the mystery of The Poisoned King. It was seriously such a good story and I’m on tenterhooks waiting for the next one!

What an absolutely beautiful and amazing book. After reading impossible creatures I was so excited to be approved for The poison king. Katherine Rundell is a genius at weaving and crafting a great story. A must read for children and adults.

How on earth do I review The Poisoned King, the second book in the Impossible Creatures series? I could simply write: buy it, read it, gift it to everyone you know! And I do mean everyone, because I think that adults benefit as much from the exquisite imagination, academic brilliance and unique ability with words of author Katherine Rundell, as the middle grade readership for which this book is written. Like one of her characters, this author 'deplores cliché' and every chapter is blessed with beautifully crafted sentences whether they are describing characters, action or those deeply held truths which reach to the heart and soul of the reader.
As stated earlier, this is the second in a series, and whilst it could be read as a standalone novel, I think that it is likely to be more enjoyable and meaningful if you have read the first Impossible Creatures book in advance (I will put a link to my review at the end of this post).
The story begins with Christopher Forrester being summoned back to the magical Archipelago by a very insistent Jacques, a small Jaculus dragon, who brings news of mysterious dragon deaths which Christopher alone has the ability to investigate. Using the ‘Waybetween’ crossing in the Scottish Highlands, of which his grandfather is the guardian, Christopher and Jacques are met on the other side by Naravirala, a sphinx who is to fly them to a meeting with the majestic dragon Sarkany. They are deflected off-course by a summons to aid a young girl whose life is in grave danger and thus Christopher teams up with Princess Anya Argen of the Island of Dousha, Duchess of the Silver Mountain, Countess of the Winged Forests. Despite her grand titles, Anya would rather be cultivating plants in the forest with her father, or speaking with a flock of royal birds, than attending palace balls and banquets with her grandfather. Having been forced to live at the palace, she has become aware of discord in the kingdom and her rescue by Christopher and Naravirala is timely.
At first it would appear that each child has a different mission to fulfill and different priorities. Christopher is deeply caring, has the instinctive ability to gain the trust of any magical creature and feels duty-bound to investigate the dragon deaths immediately. Anya burns with the ferocious anger of injustice and desire for revenge. She knows the identity of the poisoner of her grandfather, King Halam Argen. The assassin is not only a cold-blooded murderer but has also framed her beloved father, Argus, for the murder. Having narrowly escaped from being poisoned herself, and with her avian companions the royal gaganas she will use every molecule of her courage to seek justice for her father and expose the traitorous villain. It takes a wise third party to make the children realise that their goals are inter-linked, and an adventure of exceptional courage, deep friendship and encounters with mythical beasts ensues.
As I have come to expect from this author, the narrative is intricately plotted, with wonders revealed on every page, the action and emotion building to a heart-affecting climax. Additionally, I was delighted to find the necessary Belgian joke, plenty more humour and lavish descriptions of food and drink. This book is noticeably shorter than Impossible Creatures and the majority of the chapters are exceptionally short. I feel that this will make it an easier book for many middle grade readers to enjoy independently, additionally it is likely to allow teachers, teaching assistants and parents/caregivers time to read a chapter aloud even when the busy term-time agenda often seems a barrier to shared enjoyment of a book.
As well as being an immersive and exciting fantasy adventure, for those who care to look deeper I think this story provides some interesting and wise commentary for our current times. The dragons’ age-old wisdom about the dangers of gold being accumulated and concentrated in the hands of just a few men; the reflections on the power and necessity of books, libraries and knowledge; and messages about being true to yourself and choosing your own future are valuable to young and older readers. I expect The Poisoned King to be on many of the book prize lists across the coming year and I can only recommend that you share it with a child you love when it is published on 11th September 2025. I have placed my pre-order with my local indie bookshop and can’t wait to re-read the physical copy!

What an absolutely wonderful book!
This story brings us back into the world of the Archipelago, and builds on it even more. We get more places, people, and creatures, and with more of the world comes more adventure.
We start the journey back with Christopher's 'summons' back by a familiar dragon (who is fast becoming a favourite character) and once he gets there, he's met by more familiar faces. He's then given a very important task, but must aid another before he begins.
This is were we are introduced to Anya, a new character who is facing trials of her own. I loved her wildness, her love of all natural things, of the forest, and new creatures.
But then came events that caused Anya and Christopher to meet and I was invested for that point onward. I wanted to know how Christopher's task would entangle with Anya's and how they would work together once they sorted out all the puzzle pieces in their own quests.
As ever, Rundell manages to cleverly weave moral topics into the story (conversations of good/bad, save one or save the many, the price of greed etc.) that can be a great way to springboard these types of conversations within a context that children reading can relate to. I think this is brilliant - especially as I have a very mindful and curious child who will no doubt want to talk about this when she gets their copy. Very 'C.S. Lewisy',
The way this book ended was lovely. As it's pretty much all adventure, having the book end the way it did was super: as a reader I enjoyed it and as a parent of a child who will read this, I also appreciate it!
I also enjoyed (and welcomed) the expanded 'Guardians Bestiary'. With all those new characters, it was great to see this grow with those new additions!
Overall, a brilliant read that had me hooked early on, adds to the series, and will bring joy to many readers.

I didn’t think it was possible, but this sequel might be even better than the first.
From the moment a dragon woke Christopher up by chewing on his face (!!), I knew I was in for something special. The Poisoned King swept me right back into the Archipelago, and I didn’t want to leave. Katherine Rundell’s imagination is wild and wonderful this world feels alive in a way few fantasy stories do. The creatures, the landscapes, the magic… it all just sings.
But what really stuck with me was the heart of this story. Yes, there are dragons and sphinxes and epic rescues, but there’s also so much about friendship, justice, and the kind of bravery that isn’t loud or flashy, just quietly determined. I adored the girl with birds at her side (seriously can we talk about her? Instant favorite), and Christopher continues to be such a compelling, kind-hearted protagonist.
If you loved Impossible Creatures, this one will absolutely deliver. And if you haven’t started the series yet please do. Rundell’s writing is full of magic, but also humor, tenderness, and so much soul.
I turned the last page and immediately wanted to go back. Counting down the days until book three.

Phenomenal! Astonishingly imaginative.
Impossible Creatures is such a woderful book so I was really excited to read The Poisoned King and... it was even better!
Christopher Forrester is joined by the admirable Princess Anya and they go on an incredible adventure where they meet the most magical and terrifying creatures.
Fast-paced and glorious this series will go on to become a classic, will be adapted for film and will.undoubtedly capture the imagination of many children (and adults)!
Thank you to NetGalley for providing me with an ARC.

Utterly marvellous - I laughed, I cried, I added #3 immediately to my ‘to read’ list.
Katherine’s world and the creatures that inhabit it are fantastic - magical and fully formed. The characters come alive and I’m fully invested in their stories

Oh my goodness! I cannot put into words how excited I am to be back in the Archipelago! Impossible Creatures is one of my favourite books of all time. Whilst some were hesitant at the Tolkien and Morpurgo comparisons Rundell was garnering, I’m someone who believes she deserves that praise heaped upon her by the truckload. Impossible Creatures had the makings of an instant classic, and I’m delighted to report that The Poisoned King is joining it.
Mal’s absence was a big concern to me going into The Poisoned King, but boy oh boy, Christopher and his new comrade sure do work brilliantly in her honour. Anya is the epitome of those strong emotions we feel as children that we struggle to process and deal with, and when combined with the tragedy that falls at her feet, Rundell shows us a strong, fearsome yet wonderfully vulnerable companion for Christopher. I find this duo simply wondrous, and I will take much pleasure in telling everyone I know about them! (Side note: I already have told family members and friends they NEED to read this book, and I am suggesting you do the same!)
Whilst the plotline does feel suitably darker, after all the audience reading the first book will have grown up a bit by the time they get their hands on The Poisoned King, there is the lightness and dazzlement of the Archipelago that Rundell magnificently jaunts through to counter it. I want to give an honourable mention to Koo, who I one day expect there to be merchandise of and everyone to instantly fall in love with. I was besotted from his first appearance, and I WISH I could have a Koo of my own.
Between new creatures, sections of the Archipelago, characters, villains and the threads weaving to and fro from Impossible Creatures, The Poisoned King is a radiant triumph of storytelling. This book is not only a delight for readers of all ages today, but destined to shine just as brightly on bookshelves for generations to come. Furthermore, Rundell is laying the groundwork for what’s sure to be a tremendous third instalment in the series.
With Impossible Creatures: The Poisoned King, Katherine Rundell cements her place as one of the most captivating voices in children's literature. This sequel is a must-have for fans old and new. I urge you to preorder your copy ASAP and be sure to check out Rundell’s upcoming tour dates. If her storytelling on the page is anything to go by, those events will be nothing short of magical and an unmissable opportunity to step even deeper into the world of the Archipelago…

While my list of upcoming titles that I’m desperate to read is – quite naturally – different from those of many of my fellow children’s fiction-reading friends, this is a read that I suspect is on everyone’s list. The much-anticipated sequel to 2023’s Impossible Creatures, a book so brilliant that it not only won the Waterstones Children’s Book of the Year but the overall prize that year too, when I spotted that it was available to wish for on NetGalley, such was the thrill I felt that I broke out in goosebumps.
Having not been successful in my previous wishes, and being the eternal pessimist that I am, I wasn’t expecting to be approved so I was reading something else when the email came and had to wait 24 hours until I could start it but that only served to increase my anticipation when I did pick it up. Incredibly imagined and exquisitely executed, this is everything I hoped for and more as the book returns to the world of the Archipelago after the shocking conclusion of Book 1, in a story that will surely be in contention for not just Waterstones Book of 2025 but a great many other prizes too.
When we meet Christopher for a second time, it is a few months since he returned to the home he shares with his father and he is being woken up by Jacques – a small jaculus dragon – chewing on his face; not in hunger, or as a sign of affection but to alert him that his presence is urgently required once more in the Archipelago. Explaining that dragons have mysteriously been dying, Jacques tells his baffled friend that, as an outsider, he is the only human that the dragons will trust to uncover what is going on and the boy hurriedly packs a few essentials before heading to the waybetween that bridges his and Jacques’s worlds.
Arriving in the Archipelago, Christopher is greeted by sphinx Naravirala, who has come to assist him but who also tells him that there is a child in trouble, at risk of death, and that he must help her. At the same time, on the Island of Dousha, Anya, is high on the rooftops of the castle in which she lives, intent on protecting an egg laid by one of the royal gaganas – an egg that is being sought by soldiers despite the birds being protected by law. Successful in her mission, Anya takes the precious egg inside with her and reflects on the events that have led to her being forced to live within the castle’s walls instead of the forest where, as a younger child, she and her father enjoyed far more freedom, little knowing that her life is about to be completely turned on its head.
With destiny decreeing that the lives of the two children are bound together, both must seek the truth about the fate of not only the dragons but also some of the other inhabitants of the Archipelago. Joined by friends old and new, Christopher and Anya must undertake a bold and daring quest not just in their efforts to protect the dragons but also to avenge the death of the poisoned king…
I said in my review for Impossible Creatures that to call that book either an adventure or a fantasy was to do it a great disservice and that statement holds true again here. What sets that book and this one apart from other middle grades is the author’s ability to involve you in the world she has created so that you feel as though she is telling the story to you and to you alone, making you feel almost physically hooked into its narrative. Very few titles hold my attention like Katherine Rundell’s do and the further into the book I got, the greater the need I felt to continue reading – if reading were addictive, I would’ve needed serious assistance from the NHS to break myself free of the story’s pull and I know that I won’t be the only one to experience that.
You don’t need to have read Book 1 to enjoy this, but I can’t begin to stress how much more you will enjoy this if you have and are already familiar not just with Christopher and Jacques but several other characters that reappear here. Having first visited the Archipelago in Impossible Creatures, Christopher is a little older and much wiser than he was when we first met him and is more aware of the ability he has that allows him to build relationships with the animals who live there, but the crucial role he played in that previous outing has not made him arrogant or reckless as it might some individuals, making him a hero who is both entirely credible and very likeable. In Anya, he meets someone with whom he immediately feels a deep bond, but he is unafraid to tell her things as they are and prioritise his mission to save the dragons over her needs if necessary.
With the very back of the electronic copy of the book I read dangling a metaphorical carrot for the as yet untitled Book 3, expected autumn 2026, I am now left in the most desperate need of that to see how the story continues. It will, of course, be added to my list – and many others – once it is announced.
Ahead of that, the most enormous thanks are due to publisher Bloomsbury and to NetGalley for my advance, virtual read of this title. The Poisoned King publishes in hardback on September 11th and is one to preorder now.

A sweeping sequel into a magical world that is filled with magic, wisdom and adventure.
I have been anticipating returning to the Archipelago ever since I turned the final page of Impossible Creatures and I was, again, swept into a hugely imaginative world of adventure, peril and the fight to do what is right, to seek justice and to hold on to hope.
Christopher is awoken by a tiny tea-cup sized dragon chewing on the end of his nose and is implored, is quested, with returning to the Archipelago to save the dragons. Meanwhile, a new character - Anya - longs to escape the castle tower, frilly dresses and comportment lessons. But a devastating, life-trajectory-changing event, means her escape is not as she planned. And so our heroes paths are thrown together.
I adored meeting the mythical beasts familiar and new and the Bestiary at the end is a wonderful deepening of the storytelling. Spending time with familiar characters gave this a comforting feeling of being in safe hands, and although I missed Mal Alvorian, Anya steps into her space (but, crucially, not her shoes) giving us a new perspective and a new fight.
Rundell writes with remarkable elegance, using a wide and expressive vocabulary that respects young readers' intelligence. With just a few carefully chosen words, she conjures vivid scenes, offering readers the opportunity to build a world in their own imagination, making the story feel uniquely their own. No reader will experience the story the same way. It's, yet again, ingenious unmatched storytelling for children and adult readers alike.
Readers who long for escapism, magic and a path to hope, will adore this new adventure that is charged with a wisdom that will stay with you long after reading.

Like every good magical story, we begin with a boy called Christopher Forrester being unexpectedly woken by a tiny dragon chewing on his face. 🐲 Christopher has longed to return to the world of the Archipelago - the secret islands where impossible creatures thrive - at least, that’s where they used to. Dragons are being wiped out, killed by an unknown threat. As a guardian of this realm, Christopher feels a deep sense of duty to answer this call, and hurries back through the secret entrance in Scotland, to assist his magical friends in solving this terrible mystery, but alongside this, he rescues an extraordinary princess. 👸🏼
Princess Anya would much rather spend her life with her beloved royal gaganas and her beloved father in the forest behind Argentina Castle, where winged unicorns drink from the Great Lake. 🦄 A life she hasn’t enjoyed since her grandfather decided to bring her up as a royal ornament under the constrictions of the castle. But then her grandfather is murdered, 🩸 speculation falls to her father who is jailed, and her uncle sends her away whilst he reigns as Regent. Narrowly avoiding an assassination, 🔪 Anya is rescued by Christopher, and together they set out, not realising just how connected their quests are. 🦜
Overview:
✨This is a magical sequel to a timeless classic in the making. Katherine Rundell is a fantastic writer and having heard her speak in interviews, I love the grace she brings to children’s publishing, and I hope she inspires lots of kids out there to pick up, what perhaps might be their first ‘grown up’ book. There are big words and I love that young readers are challenged with an expansive vocabulary. 🤓
I wish this book every success with publication, and I look forward to receiving my hard copy in the post upon release!
Pick this book up for yourself or your kids!

A Spellbinding Return to the Archipelago
I am beyond thrilled to have received an advanced preview of this incredible book—my heartfelt thanks to the publishers for the opportunity to dive back into this world before its official release. From the very first page, Katherine’s writing swept me away once again. Her storytelling is nothing short of masterful—easily standing shoulder to shoulder with greats like Philip Pullman.
I won’t add any spoilers!!
When Christopher Forrester is unexpectedly woken by a miniature dragon chewing on his face, I knew we were in for a wild, magical ride. What follows is a whirlwind of adventure: a daring rescue atop a sphinx and a confrontation in a dragon’s lair. It’s all written with such vivid imagination and emotional depth that I found myself grinning, gasping, and holding my breath from chapter to chapter.
Katherine has crafted a world that feels both ancient and fresh, full of wonder and danger in equal measure. It’s a rare gift to capture the mythic and the human so seamlessly—and she does it with elegance and heart.
I felt so privileged and ecstatic to receive an early copy, and I cannot recommend this book enough. A must-buy for fans of the series, and for anyone who still believes in the power of stories to transport, transform, and inspire.

I absolutely loved Impossible Creatures and couldn't wait for the follow-up, though felt it was some act to follow. As it turns out, my only criticism is that it wasn't nearly long enough. I could have read four, five times as much! I'm not going to rehearse the plot details, more appreciate the quality of the writing. It is an extraordinary feat of imagination, sure, but I really think what sets it apart is the warm humour that runs through it. The character of Jaculus, the tiny dragon (with a big chip on his shoulder) is a truly marvellous creation.
Now, how long until part three??

The Poisoned King is a brilliant sequel to the first book, I actually enjoyed it even more, which is a rare thing. The book is beautifully written, the characters are magical and interesting (and I very much appreciate the glossary of magical characters at the end of the book!), the storyline was great, I love the dialogue and it was fast paced. I read the first book together with my 9 year old, and I she will definitely want to read this book too.
It follows Christopher as he returns to the Archipelago to help save the dragons, and introduces a new character / storyline via Princess Anya of Dousha and her quest to save her father, along with old favourites - Jacques (the Jaculus dragon), Nighthand, Irian, Naravirala and my personal fav Ratwin.
Thank you to NetGalley and Bloomsbury for an advanced copy of this book in exchange for my opinion (which is all my own).

Impossible Creatures returns with the second instalment: The Poisoned King. With dragons, murders, and kick ass characters, what is not to enjoy? A great adventure in the Archipelago. Hoping there will be a book there!

What a wonderful follow-up to the first book and this one I enjoyed more than the first one. I read this in an afternoon and didn't want to put it down. I'm hoping there will be more. My thanks to netgalley and the publisher's for giving me the opportunity to read this book in return for an honest review.

Another excellent trip to the Archipelago. I loved this as much as Impossible Creatures and especially liked the edition of Anya, Gallia and Koo.
I look forward to recommending this to my Year 7s.

I have been so impatient to return to the Archipelago despite the heavy grief after the first instalment. I missed Christopher and Jacques so so much and even though it felt like a bit of an effort to let new characters into my heart, Anya and her gaganas are spectacular and precious. It felt like returning to Narnia: a year had passed and Christopher had created a life in the Outerlands, unable to shake the memories of Mal and everything they did together until a particularly tiny and obnoxious dragon summoned him back into the fray. And all it took at the end was for Christopher's name to be uttered by a certain someone and I started to cry. There is something about the way this world has been built and how deeply you are invited to care about it all.
I love how these books do not shy away from rage and fury and sacrifice and bloodshed, that the main characters might be young but they are full of power and the clearest understanding of how to do what is right.
My only criticisms would be that elements of Anya's character felt a bit cliche and parts of the story felt rushed, not in logic but the pacing was so fast I felt a bit bewildered at times towards the end.
This book was also full of the same deliciously smart and blunt sense of humour that makes it feel like you're part of their world for being able to understand it all. And despite all the dangers and the risk of dramatic death, I loved getting to be a part of their adventure especially when it involves saving dragons and dealing with a malicious member of the royal family.
Thanks to Netgalley for making my day with this arc.

In this sequel, Christopher is summoned back to the the Archipelago when the dragons start mysteriously dying. He also helps a young princess avenge the murder of her grandfather the king.
This author never fails to achieve! Old characters are skilfully developed, new characters add extra depth. The writing is beautiful, the plot fast moving, the whole keeps the pages effortlessly turning. Wonderful

Title - the poisoned king
Author - Katherine Rundell
Release Date - September 2025
Page Count - 336
Read/Listen Time - 7hrs
Brief overview - an excellent follow up to the outstanding impossible creatures
Rating - ⭐️⭐️⭐️⭐️ /4 stars
Impossible Creatures was a stand out for me in back in 2023. Not since the Harry Potter series have I been so enamored by a children's book. The Poisoned King is an excellent follow; I was worried given the ending of the first book. In The Poisoned King we are introduced to some new characters and fantastical beasts; some old friends are thrown in there for good measure too.
Anya is an amazing young princess who flees for her life following a heinous murder. She meets up with William, and together they go on a journey to save Anyas father, the dragons, and the entire future of the archipelago.
An outstanding read and one for the bedtime storytime with the kiddies. Loved it.
Thank you you @netgalley and @bloomsbury for the early e-arc in return for an honest review.

In The Poisoned King, Rundell plunges us back into the magic of the Archipelago, full of fabulous creatures, witty writing, and good old-fashioned adventure.
The book begins with Christopher being summoned back to the Archipelago to save the creatures he is sworn to protect. His journey soon intersects with that of Princess Anya, who he saves and helps to avenge a poisonous plot. Along the way, Rundell introduces us to new magical creatures alongside some old favourites.
I liked Princess Anya, who was interesting, sympathetic, and thankfully largely (but not entirely) devoid of Rundell's tendency to make her female protagonists disgusting. Like Impossible Creatures, The Poisoned King ends with a somewhat didactic moral lesson.
In the end, I really enjoyed The Poisoned King, though it felt like a standalone adventure separate from and less original than the first book. I really look forward to Book 3, which I hope will pick up on the plot line hinted at in the last chapter! Overall, the Poisoned King is a worthy sequel for fans of Impossible Creatures!
Thank you to the publisher and Netgalley for an eARC in exchange for an honest review.

This really is a worthy sequel to the first book in the series, titled Impossible Creatures. Christopher has been longing to go back to the magical archipelago that he is tasked with helping to protect, even though he is an Otherworlder, belonging to our own sphere. But he doesn't know quite what he is getting into this time...
Caught up in Princess Anya's quest for justice as she attempts to deal with a foul plot, Christopher encounters a host of amazing creatures. Indeed, at times it feels like too many!
The story begins with an excellent hook, and Koo is an adorable addition. The adventure is engaging and the ending is also well done and leaves the reader eager for more. This series is shaping up beautifully and is worth checking out for any reader.

Loved the start and end of this, the characters of Anya and Christopher are brilliant and can't wait to see where the story goes next. The ending already has me looking forward to book three. I think perhaps a little bloated in the middle, it felt quite info heavy with characters thrown in just to hit the impossible creatures brief. I think anyone who likes mythology and mythological creatures would really enjoy this and get lost in the world.

Thank you to Katherine Rundell, Bloomsbury, and NetGalley for the e-arc in exchange for an honest review!
A sequel to Impossible Creatures, The Poisoned King follows the adventures of Christopher, an ‘Otherlander” (our world) charged with protecting the Archipelago, and Anya, a princess wishing to avenge a poisonous plot.
TPK was an engaging read with strong vocabulary aimed to stretch middle grade readers, much the same as with Rundell’s other novels. It read well, the plot was interesting and paced perfectly, and the world-building was just as excellent as the first novel. Anya could come across a little cliché and trope-y at times but it didn’t detract from the enjoyment of the book. I liked the tie-in with several plot points from the first book at the ending and look forward to the next instalment!

My daughter has been a Katherine Rundell fan since she read The Explorer. She was very excited to have the opportunity to read The Poisoned King. Her review is below.
A well made book, skillfully written.
The start was an instant hook, I couldnt put it down, and the characters are very interesting, I especially like the new heroine, the banter between them all is very enjoyable. I like how it brought back old characters and added new ones, Koo was very cute and the ending part was very emotional and powerful. A few of the flaws were that some parts of the plot and the ending were quite guessable. Overall a great sequel to a stunning series.

This is the second title in Rundell’s Impossible Creatures series. While someone new diving straight into the book may be slightly confused as to what is happening, they will soon pick it up, as will a seasoned fantasy fan, but the good thing is there is no patronising recap which often happens with sequels.
Christopher returns to the Archipelago, summoned by a dragon worried about the deaths of other dragons. We meet again some of the mythical creatures who featured in book one. Mal in book one is referenced, but doesn’t make an appearance. Instead we have an equally fiery, independent female protagonist in Anya, Princess of Dousha. Anya had loved living in the forest with her Father, but her Grandfather decided she was too wild and brought her to live in the castle to be educated in the ways of Princesses. Despite this Anya still manages to care for creatures, rescuing the egg of a Gagana so it hatches before royal soldiers destroy it.
When the paths of these two children intersect they are both determined to right a wrong, each willing to help the other after their own cause is solved. But what they begin to understand is that both quests are intertwined and working together will reach the same solution.
Christopher in this book understands more of the duties of a Guardian of the Archipelago. Anya, having experienced a bereavement, at first burns with revenge but does not sink to the level of the villain when deciding their fate and reasons this out thus giving those quick to judge pause for thought.
There is adventure, suspense and of course brilliant writing. Conservation is a strong theme, albeit of mythical creatures, but the message for our world is easily translated and children will pick up on this immediately. Not normally a fantasy lover I make an exception for Katherine Rundell because she doesn’t speak down to children, subtly educating them (and me) without preaching.
The chapters are short making it a slightly easier read than the first scene-setting book, but this still remains a meaty read for children of 10+ or a great book to read aloud to years 5-7. Black and white chapter headings are promised for the hardcopy but the cover is as vibrant and exciting as the first.

Absolutely phenomenal! What a joy it was to return to Archipelago for another whimsical, high-stakes adventure. I truly love how Rundell encourages a love of nature and conservation in her younger creatures through her wonderfully unique and loveable creatures, alongside her strong-willed and caring characters. Truly a job to read!

This is a book for adults who want to read a children's story reminiscent of C.S .Lewis and for children who want an adventure with the most glorious magical beasts. Written as a sequel to the highly acclaimed "Impossible Creatures", this new story takes us again into a fantasy world of kings ,oceans, magic and quest underpinned by philosophical musings but lightened by wit. In this tale Christopher returns to the world through the lake to save the dragons who are inexplicably dying. Meanwhile the princess Anya witnesses the death of her grandfather ,the King of the realm and sets out to seek justice for him. Inevitably the two children meet and work together. Unlike many of the current fantasy adventures this is more restrained in terms of the emotional journey the children go on but this is no bad thing. In its place is much detailed and vivid description of the creatures and their surroundings which are sure to spark imagination. Put simply, this is very good.
My thanks got to Bloomsbury and to NetGalley for this advanced copy.

Arc received from Net Galley in exchange for an honest review.
I LOVED this story - possibly not as much as I loved the first book, but I was so happy to be transported back into this world again. Rundell’s world-building is just exquisite, with new and old characters making appearances as well as the plethora of creatures that I loved.
Christopher is back in the Archipelago again! Summoned by Jacques, Christopher must find out what is killing the dragons and if he can stop it. Along the way, he meets Anya. Though different than Mal (who I did miss), she is a fiesty, good-hearted child who has experienced a great tragedy in her kingdom. The lives of Christopher and Anya entwine, with their stories and missions meeting each other and connecting thoughout the novel.
It was lovely to meet Irian, Nightmand, Naravirala, Ratwin and Jacques again, and I enjoyed meeting the gagana and Arach. I think Rundell finds a way to introduce quite a few characters in a short space of time, but you don’t lose track of who she’s talking about. With the creatures, there is a handy guide which you can use to refresh yourself if you forget their characteristics. I would have loved to see more of Nighthand and Irian in the book than I did, but I enjoyed their contributions, particularly towards the end of the book.
Overall, this was a joy to read and 2026 can’t come fast enough for the next in the series!

Really enjoyed this second book (maybe a little less than the first one; I missed the dynamic between Mal and Christopher), it is a great return to the universe of Impossible creatures!

An enjoyable return to the wonderful world of the Archipelago.
The book opens about a year after the events of Impossible Creatures. Christopher has returned to his everyday life but still dreams of Mal and has a bag packed ready to return to the Archipelago. When dragons start dying in suspicious circumstances it is decided that Christopher, as an outsider, is best placed to help.
Alongside this quest to discover what is causing the deaths, Christopher is asked to help Princess Anya. Brought up in the forest she has found it hard to adapt to royal life and prefers the company of her beloved gagana birds to people. With Anya's life in danger Christopher comes to her rescue and she gets involved in his efforts for the dragons.
I really enjoy Katherine Rundell's writing. She is a wonderful storyteller who can create beautifully vivid scenes. I love that she includes words that children are unlikely to have come across and will likely need to look up. It's always in a positive way that makes you want to know about the word, rather than being a barrier to enjoying the story if you don't understand it.
The story encourages readers to continue on with the book. Chapters are short and each leads on to the next in a way that makes it difficult to find a place you are willing to put the book down. The mythical creatures are again the stars of the book for me. My advance copy didn't have all the artwork, but based on the first book I am sure it will be wonderful.
I didn't enjoy this story quite as much as Impossible Creatures. I found Anya quite unlikeable, even more so than Mal was in Impossible Creatures. Her behaviour is awful and I found one scene in particular quite unsettling. I realise she is a child and that books offer a way for children to get to grips with their emotions but I felt that went too far. I will say that the overall message of the book is very much about not choosing violence and there is character development.
The whole story with Anya's family felt too simplistic. It was bizarre that everyone just went along with things and no one was suspicious of the person who actually stood to gain. Likewise the ending to that plotline was also tied up in a very 'and they all lived happily ever after' fashion. This book seems to be written for a slightly older audience than the first as it deals with some more mature issues. Therefore it was disappointing that the subplot rather glossed over things.
Where the story shone for me was when the focus was on the mythical creatures themselves. The descriptions are vivid and I love that they go beyond the basic species you might expect. The non-human characters were my favourites. Some of the new ones in particular were fabulous. You really want to escape to the Archipelago and live there yourself.
An enjoyable fantasy adventure.

As a teacher, I’ve used many of Katherine Rundell’s books as part of our curriculum and love her style. She has a very clear style of writing which I enjoy and think is a great example to children (learning to speak correctly and write well).
I enjoyed this book more than the first in the series to be honest. I found this one really fast-paced and action packed in a way that was easier to follow than the first. I liked how we revisited events and met people from book 1.
The characters, as in all her books, are likeable and rebatable for children. They would feel what the characters feel and the added bits of humour always go down well with my middle grade children.
I look forward to putting this in our library when it is released and building the hype for book 3-5!
