It was my first 5 star read of this year. It's overall a light read that might work really well for fans of T. Kingfisher and Someone You Can Build a Nest in by John Wiswell. It has folklore elements and mixes elements of horror with a sense of humor and cozy moments.

I love the trope of looking at the world and humanity through the eyes of what people deem to be a monster, and found family is one of my favorite things in books so it definitely was a story for me. It also has a dog and Kingfisher-like sense of humor.

I'd only say, don't expect a highly convoluted plot or high action, it was more of a light, palate cleanser type of read, reminiscent of a fairy tale for adults,and I very much enjoyed it for that. I started caring for the characters quite a lot and the ending made me tear up.

I'll admit, I might have been hoping for a sapphic storyline, but it wasn't the case - it made me a bit sad but I also appreciate how it was actually done.

I’m a huge fan of T. Kingfisher’s books and am always on the lookout for more fantasy that shares her style. Greenteeth by Molly O’Neil is exactly that - a charming, cosy debut novel that is an absolute delight to read.

This book is told in the first person with Jenny as our narrator. An ancient lake monster who just wants to mind her business, her peace is disturbed when the villagers throw a suspected witch into her waters and she makes an important decision - she saves the witch. This spurns her to leave her lake and send her on a wonderful character arc. I loved seeing her grumpy facade slip as she grew closer to her companions. She is, however, very much not human and this is a theme explored in the story. She is also more than a monster - she has depth of character and I just adored seeing the story through her eyes.

I loved the setting and the world that O’Neil creates in Greenteeth. She works with existing British folklore and weaves a tale of fae and mythology that spans across Britain. Jenny’s lake, the countryside the crew traverse, and the fae creatures are all a delight and so vivid. The addition of some of my favourite tropes - found family and a good old fashion quest - make it a fun, cosy, and compelling tale.

The book slows down a little in the middle and there were some choices with one particular character that I didn’t love, but otherwise Greenteeth is a great cosy fantasy for people like me who want a bit of teeth to go alongside the cosy vibes. If you like T. Kingfisher’s fantasy stories as well as cosy fantasy that still involves limbs being forcibly removed, Greenteeth is the book for you. I can’t wait to see what she writes next!

A lake monster, a witch and a goblin battle the oppressor. Magical quest meets Arthurian legend. Fun. Superficially this is cosy fantasy, but it also has surprisingly sad moments and is deeper than expected, tense and a little scary at times. If you know your way around the folklore and mythology of the British Isles, you might get a clue early on where this is headed, but it didn‘t harm the story telling. I kept me hooked and guessing. Nice mesh with German folklore and myth. A rather shocking event towards the end. Nicely done debut.

I would definitely read more by the author. Thoroughly enjoyable. Found family, female empowerment, unlikely friendship, a cute dog and the fair folk. And musn‘t forget the pike and the underwater scenes.

For the first 40% and 10 chapters I read the ebook and then started to alternate between ebook and audio. Well done audio, I liked the narrator.

Pretty cover!

I received an advanced copy of this book in ebook and audio format from the publisher through NetGalley. All opinions are my own and I was not required to give a positive review.

Wow, this is a debut?

I adore everything about this book and it is very fitting that it has a blurb by T. Kingfisher on the cover! This novel about a lonely mythical creature, a witch and a merchant who suddenly find themselves in a fight against the Erlkönig (I had to supress a scream because I grew up in a town in Germany where we have a lot of Erlkönig-places). was not only entertaining but also gripping and thoughtful in so many aspects.

I loved how the journey not only involved a way to find a weapon against a strong enemy but also friendship, social cohesion and hardships on the way. Molly O'Neill is able to make her characters relatable and lovable even if they are only on page from time to time (like the king and queen of the faery court) or not at all (like Temperance's husband and children).

Another great part about this book is how folklore and legends are combined, how hints are strewn throughout the story and yet there as a reader I was still very interested in how excactly O'Neill would combine the different throngs of her narrativ. And I wasn't disappointed at all! I knew some time before the ending that something with king Arthur and Merlin has a connection to the story of our unlikely heroes but I wouldn't have guessed Jenny Greenteeths role in it.

With themes of regrets, also about some inactions with regard to the disappearing of magic and magical creatures where handled so well and I will love to read more by Molly O'Neill!

I already ordered myself a copy of the book because I want to have it on my shelves.

Molly O'Neill's debut "Greenteeth" is a carefully crafted exploration of British folklore and mythology, reimagining a feared water spirit as a complex protagonist navigating a magical and challenging adventure. When the lake-dwelling creature Jenny unexpectedly comes to the rescue of a drowning witch named Temperance, a legendary adventure begins, blurring the lines between what it means to be a monster and what it means to be a hero.

Perhaps this book's greatest strength is its detailed world-building, drawing inspiration from British and Welsh traditions. The story comes to us through Jenny Greenteeth, whose monstrous perspective offers you both a sense of danger and deep emotional resonance. The unexpected friendship between Jenny and Temperance is a touching look at how forged connections can overcome even the greatest differences.

It is a great story on the order of The Hobbit (the original), with an unlikely band of friends questing to save the life and land they love. I read it in one long sitting and I was rewarded for my efforts. The story is well-paced and weaves a more complex story than you might expect from the blurb. Without giving any spoilers, if you are a fan of fae lore, Arthurian legends, or other British and Welsh mythology, you should read this book.

"Greenteeth" will enchant anyone looking for fantasy folklore with mythological richness rather than the traditional romantic tale. It will resonate particularly well with fans of T. Kingfisher and those who enjoy magical settings that offer fresh takes on classic tales.

Thank you to Orbit and NetGalley for providing an eARC for my review.

Special thank you to Littl Brown Group / Orbit Books & Netgalleg for letting me emerge myself into this beautiful book ahead of release day !

4.5 / 5

Molly O'Neill's Greenteeth offers a refreshing reinterpretation of the classic legend of the monstrous Jenny Greenteeth, a water hag, said to lurk beneath the surface of ponds and rivers, waiting to drag vulnerable victims - such as children and the elderly —to their watery graves. While retaining Jenny's aquatic origins and solitary nature, O'Neill transforms her from a fearsome predator into a complex, morally ambiguous protagonist that is more relatable than we might want to admit!

In the novel, Jenny's life takes an unexpected turn when she rescues Temperance, a village witch wrongfully condemned by a malevolent pastor. They then embark on a quest to save their beloved village, joined by Brackus the goblin and an adorable pup named Cavall, entering the world of Fae on a level no other mortal has in the last few centuries!

This story is incredibly cosy and definitely met my expectations! I found it easy to visualise the characters and the world-building was beautiful. I couldn't help but think I might be a Jenny deep down! It was humorous, with elements of good banter, and had me giggling under the blanket at times. There was no sense of heavy politics so it is a very easy read which is exactly what I needed.

As someone who isn’t originally from England but have lived here most of her adult life, I enjoyed learning about some Arthurian legends whilst our protagonists were on their big quests. This was also my first time hearing about Jenny Greenteeth and some of the other characters such as Gwyn ap Nupp, which made me really excited to get on with the story and learn something new that I can possibly teach my kids in the future.

Greenteeth is very straight forward and exactly as you would expect it; a creature ends up on a quest with the most unexpected characters and they become friends for life. Come on, who doesn’t love a Found Family trope? I sure do!

I was promised a cozy and delightful book and O'Neill definitely delivered. I would say this is exactly what I was looking for! The folklore background of the story really pulled it all together and overall I had a very great time reading this book. After the beginning of the book I felt like there was a slight lull, but soon after it thankfully picked up again. Would highly recommend this to lovers of cozy fantasy and fantasy creatures embarking on a magical mission!

Book Review: Greenteeth by Molly O’Neill
⭐️⭐️⭐️⭐️✨ (4.5/5)

Molly O’Neill’s Greenteeth is a haunting, lyrical novel that lures you in like a dark fairytale whispered at the edge of a misty lake. Blending folklore and modern-day suspense, the story revolves around the sinister legend of Jenny Greenteeth — a water spirit said to drag the unwary to their doom — and the tense, eerie relationship between the two central characters, Jenny and Temperance.

Jenny, a woman forever linked to the folklore of her small, isolated village, is both a victim of rumor and a force of nature herself. Temperance, an outsider in many ways, finds herself caught in the tangled web of local myths, half-truths, and dark secrets. As the novel unfolds, their fates become more and more entwined, with the story expertly walking the line between supernatural horror and very human fear.

O’Neill’s writing is rich and atmospheric — you can almost feel the dampness of the water, hear the rustling reeds, and sense the silent weight of something watching beneath the surface. The novel’s strength lies not just in its chilling moments, but in how it explores grief, guilt, and the way small communities can turn both protective and hostile in the face of the unknown.

If there’s any slight flaw, it’s that the final confrontation felt a little abrupt, especially after such a slow, suspenseful build-up. I would have loved just a bit more time to let the climax breathe. Still, the emotional resonance and the way the novel blurs the lines between myth and reality are masterfully done.

Greenteeth is perfect for fans of dark, magical realism and unsettling small-town mysteries. It’s the kind of book that lingers with you long after the final page — like a whisper in the reeds or a ripple on the water’s surface. Highly recommended.

Thank you Netgalley and Little, Brown Book Group/Orbit for the chance to read an eArc early.

3.5⭐ rounded up.

Greenteeth is a fun questing adventure with a simple set of characters set in the Arthurian era. I loved the different folklore/legends the author included. It was fun to read about the characters adventuring all over the UK encountering various different fae.

The pacing was a little on the slow side meaning indie myself not as gripped by the story as I wanted to be. The ending picked up speed though and I really enjoyed the encounter with the villain.

Fans of questing adventures will definitely enjoy this book!

This was incredibly fun, gentle fantasy novel. It doesn't drag, but carries itself at a comfortable pace that keeps you steadily moving along.
It blends together elements of a classic heroic adventure, folklore and fantasy beautifully.
While the ending became reather easy to predict once arriving at the final chapters, I still had fun, and reguardless of my guessing the ending I still found it satisfying and altogether worthy of a high rating.
Jenny, as a protagonist, is wonderful - a creature from a lake who is forced out of her home in order to save it only to change for the better as a result of that trouble. I adored her, and Temperance, so much I feel sad to let them go.

Overall, this was not a bad debut novel. It was a promising folklore inspired story, and I liked many of the unusual fae descriptions. However, it lacked in some aspects.

I would not say it's low stakes, since the UK and the world as a whole is at stake, so cozy fantasy doesn't feel quite right, but it's not an epic fantasy with battles either. This started more cosy, then started to move towards higher stakes, but never felt like it properly fulfilled either option.
It was a a slow, cute story about found family, with no romance.
However, the pacing did feel odd at times. It was essentially just 3 lame (imo) quests one after another, all kind of predictable, and SPOILERS ---- it was clear from the start it was going to be pretty useless too, with repeated mention of chekov's sword----.

Jenny felt like a great complicated character, however the side characters felt a bit flat, and I would've really liked to see Temp's family reunite on page or even mention her seeing them before the battle or something. Maybe some of the motivation for Brackus too.

Both the pacing and character types, made it feel like a sort of DnD campaign.

I both read and listened to the audiobook for this one, and the following is reviewing solely on the audiobook.
While her audio did a good job at differentiating characters, and was very clear, I feel like there could have been more emotion in her narration. I don't think the text was as calm as the narrator sounded, but I may have interpreted it differently. For such a monstrous being she sounded a little too upper-class-modern-day human, to me.

Thanks to the author, publisher, and NetGalley for the ARC.

If you like Welsh/English mythology, this book is for you! It reminded me of cosy fantasy books due to lovable characters. Even tough the stakes were high, I didn't feel like it. Overall a very nice book to brighten your evenings.

3.5 stars

This book never would have been on my radar without Netgalley. Some books are promoted all over the internet, but for some reason this book is not that visible. Which is a pity. The cover looked really intriguing, albeit a little scary too, and the summary made me really curious about the book. I was at least really happy that Orbit granted me a review copy and with the release date almost there, I could finally dive in last week.

This book is absolutely perfect to cure your Emily Wilde hangover. The two book series have, in a way, a lot in common. Both books are about the faerie folk, both books are talking about quests and traveling and both books have a cosy and yet also sort of sinister vibe. It's hard to describe, but this book was the best of both worlds. It was a lighthearted book that focussed mostly on friendship and adventure, but it did have a more serious and darker undertone and a spectacular finale.

What I especially loved about this book is the perspective, and main character. Instead of following a human stumbling into a fantasy world, we focus on one the faeries the human meets. She's telling us her stories. We're reading her thoughts. And it may sound weird, but in a way it made the book even more endearing. Jenny is a unique character, she really shines and despite her flaws and mistakes, it's hard not to like her.

This book also contains surprisingly much folklore, myth and legend. The more familiar you are with all the Welsh, Scottish and English tales of faerie, the more amazing this book will get. And despite the fact that the author included so many tales, it never felt overwhelming or all over the place. Everyone we met, every part of the quest, every magical power, it all made sense and it all fitted seamlessly into this story. I would certainly love more books like this!

I was going into this book thinking this will be in the same vein as T. Kingfisher, but I think on reading it, it may be actually more in vein of John Wiswell! Both are very good writers with their own set of strengths, and evoking this debut in same breath hopefully conveys the idea of the kind of story Greenteeth: non-human POV that allows the reader to have a sideways perspective on humanity, a strong focus on found family/friendship bones and a really solid helping of mythology and folklore themes, If you like that kind of stuff, do not pass by this debut: I really enjoyed my time with it, and looking forward to more from the author.

Thank you to Orbit for my review copy.

3 stars

This book is full of folklore references to myths and legends of the British Isles! I adored seeing which ones I could pick out (and I LOVED that there was one mention to one of my favourites! (The creature in question is Peg Powler and it really made me smile when I read the very small reference to her!)

This is the first time I have read from a non-human perspective in a while and it was interesting to read from something that isn't human, however, at times, it felt like Jenny wasn't too monstrous, but I loved her interactions with Bracken and Temperance, even if some of the dialogue felt a bit stilted to read.

The pace of this is definitely on the slower side, and when I got to the part where the plot begins, I could very easily see where it was going. The plot was mainly a typical quest plot to stop the big bad, so at times, it felt like a sludge to read through because I knew how it was going to end.

Overall, this is a cozier mid-fantasy quest book, with some lovely descriptions of forests and moors and full to the brim with mentions of folklore, so if this seems like something you'd enjoy, pick it up!

A clean pond, organized frogbit and now and then a nice carp to snack on is how Jenny Greenteeth likes to see it.
As any other Greenteeth she stays in her waters and lives a fairly solitaire life. Until someone is thrown into the water and left to drown.

What follows is a very enjoyable journey and adventure. Jenny is VERY obviously not a human and I loved reading the parts that shows how much she differs. The fact we follow her, and not a human who observers Jenny is what makes it all the more fun. The stakes are not high but also not low so there's enough adventure for everyone while we follow Jenny.

Greenteeth is like a little adventure and journey you can enjoy while being bundled up cozy on the couch with a nice blanket.
If you love reading about English folklore and myths, along with going onto adventures like in The Hobbit and Percy Jackson, with a dash of fun human and not-human interaction then this book is definitely for you! I am for sure gonna recommend this book to some of my friends or gift it as a birthday present.

The book might be promoted as cozy and while it does have those elements it is a more an adult book with some parts that might make some uncomfortable. Nothing too visceral but it's not cozy-cozy 'low-to-none stakes' as Legends and Latte's for instance.

Greenteeth is a debut cosy fantasy book about a lake dwelling monster called Jenny Greenteeth and the adventures that her and her companions go on. I loved this book and thought it was such a wonderfully written story.

Jenny Greenteeth is a unique main character, she is a lake dwelling monster who has lived for over hundreds of years. I loved reading about her especially the descriptions of her lake, I really felt how much of a home it was to Jenny and how important it was to her. Temperance is a headstrong character who's willing to do anything to get back to her family and I loved reading about her and Jenny meeting after Jenny saves her from drowning.

I loved the focus on friendship in Greenteeth, there is no romance in this book. At the beginning Jenny, Temperance and Brackus are kind of thrown together to go on this quest and as the book goes on their friendship grows. Each one of the characters comes to rely on the others and it made for such a beautiful emotional story as they learn to open up to one another and become a found family.

The plot drew me in and I loved reading about the different trials the characters had to go through to take down the evil that's took over their home. The creatures they encounter along the way were interesting and I liked how the book is based on forklore and mythology. The writing was very compelling and I was very engrossed in the book from start to finish.

Overall I loved Greenteeth especially how much it focuses on friendship and the importance of it. Jenny Greenteeth is a unique and memorable main character who I loved reading about and the writing and story captivated me. I'm excited for future books by this author since I enjoyed Greenteeth so much.


(I was sent a Netgalley ARC of this book to review)

Greenteeth follows three unlikely friends - a sea hag called Jenny (our POV character), the witch Temperance and a goblin called Brakus - as they go on a series of trials to get a weapon to fight a hellscape demon called the Erl King. I throughly enjoyed this take on an epic quest. The setting was around the time of the religious reformation and other witch trials in the UK (1600s-ish) and the characters journey across the British Isle, visiting with different mythological and folklore characters and creatures.
Molly O'Neill tells the story well through Jenny's POV, a character who is quite isolated and around for hundreds of years. She's an unlikely character to follow but Jenny was entertaining and engaging.
Within the quest style storyline, there is also hints of a discussion around judging a book by its cover, especially in Jenny's case, and morality not being as simple as others make it out to be. It would have been nice to explore these further, but I also understand this wasn't the point of the story and was more about friendships, found families and those relationships.
Overall, a story I devoured and I'd be interested in reading more by O'Neill in the future!

Thank you to Molly O'Neill, Little Brown and NetGalley for providing me with a copy of this book in exchange for a review.

Greenteeth is a tale of adventure and magic for those who like stories based on folklore and Arthurian legend. If I had to describe this book in one word, it would be green. The characters spend a lot of time walking so the setting for most of the book is forest. I can imagine this would make for a good read in your local park, under a tree on a warm spring day.

Jenny Greenteeth is a river hag from English folklore who would pull children or the elderly into her lake and drown them. She was most likely created to scare children away from dangerous waters covered in duckweed which completely obscures the surface of the lake.

I liked Jenny as a character, I found her to be both charming and amusing. It was fun to read a story from the perspective of the monster instead of the human, even if they do eventually end up cooperating. At times Jenny was a bit difficult and quite juvenile in the way she resolves conflict, but ultimately she is an engaging character with a unique voice.

Jenny is hundreds of years old so there's plenty of possibility for more stories from her life which I would definitely read, especially when she was with her daughter Little Jenny (not a spoiler, don't worry).

There's no romance in the novel which I would say is a plus. The story focuses on the friendship between Jenny and Temperance with lots of discussion on what makes someone a monster or a human and how sometimes we can be a bit of both.

My fancast for Greenteeth:
Anya Taylor Joy as Jenny
Olivia Cooke as Temperance
Billy Boyd as Brackus

Greenteeth is Molly O'Neill's debut novel and it comes out 25th February 2025.

I give Greenteeth 5 stars!

an unlikely found family embarking on a seemingly impossible journey in order to save their village from an infamous and elusive evil.

Unfortunately, this story fell somewhat flat for me. I found myself feeling as though it was just going through the motions of a rather basic story; even elements which were clearly intended to surprise or shock the reader seemed a little lacklustre.

Perhaps my opinion is a little biased, as lately I have read a few other books featuring a non-human main character, so Greenteeth has had some big boots to fill. Someone to Build a Nest In and The Morrigan are two books which I thought executed this trope a little better than Greenteeth, and so the latter has paled in comparison due to being read in such quick succession! Or maybe I’m just tired of this kind of story? Either way, I just wanted to mention this as a little disclaimer! These types of books seem very popular lately and I suppose the novelty has just worn off a little.
