This book had me intrigued from the very beginning. Trials, blood-bonds, and fate ensconce the pages from practically the first page which made this book a perfect binge-worth read.

The stakes were high and the pace was fast with very little down-time throughout the entire story. Something always seemed to be happening to move the story forward, whether that be the trials of The Ridding itself or through terror and escape from syphons, fiendlings or other supernatural elements.

I loved Caldwell and Cavendish, with their dark humour and dead-pan comments, and also Vesper with her feisty attitude and sheer spirit and will throughout the story. Although I loved these characters, Lonan for me was the real star. His whole demeanor and protective side had me rooting for him the whole way. I only wish we would have had more from his POV.

The romance angle was interesting, I loved the idea that not all blood-mates were what you'd want or the swoon-worthy love story that we usually see in these kinds of books where the FMC and MMC are fated to be together and live happily ever after.

Some closed door romance scenes, with zero spice would make this book appealing to both young adults and adults alike with a fun story about choosing your own destiny.

Thank you to the publisher for allowing me to read an advance copy of this book via Netgalley.

After loving Seven Deadly Thorns, I couldn’t wait to dive into Twelve Dark Hours and it absolutely delivered.
This is a fast paced YA fantasy that throws you straight into a high stakes, survive the night adventure where every hour counts. Once the story finds its footing, it barely slows down, delivering relentless action, danger, twists and genuinely creepy moments that kept me turning the pages. Totally consumed my day!
Vesper is a determined and compelling heroine, while Lonan completely stole the show for me. His unwavering loyalty, protective nature and slow burn chemistry with Vesper made every scene they shared worth savouring. Their banter was one of my favourite parts of the book.

Amber Hamilton continues to create an imaginative fantasy world packed with dark magic, blood bonds, supernatural threats and memorable supporting characters. The pacing is excellent, making this an incredibly bingeable read that left me eager for whatever comes next.
If you enjoy fast moving fantasy with high stakes, found family, slow burn romance and dangerous magical trials, this is one to add to your TBR.

If you enjoyed Powerless by Lauren Roberts, The Prison Healer by Lynette Noni,Lightlark by Alex Aster then this is a must for the tbr. 📚✨

Thank you to NetGalley and the publisher for providing me with an advanced copy in exchange for an honest review

YESS!! I was so excited when I saw another book by Amber Hamilton as I flew through Seven Deadly Thorns and was captivated by the world.

The minute I got approval on Netgalley I stopped all other reading to start Twelve Dark Hours and was completely captivated!

I love the way AH writes, the plot is fab, all the characters have a purpose and you can connect with them (which I prefer over stories with so many characters I'm having to take notes to work out wtf is going on).

I love the connection and banter between Vesper and Lonan, and the twists throughout (I don't want to put any spoilers).

This book has been written with so much love and emotion and it is evident in the way the story unfolds and for me it was just perfection.

Thank you so much for the ARC! I thoroughly enjoyed Hamilton's new book! I liked her Seven Deadly Thorns, and I liked how she stuck to the same vibe for this one.

The books are not related, however they take place in the same universe; and I do like the numbers on their titles. She has a whole fairytail universe to explore in this way, and I cannot wait for the next!

Is not a book to reinvent the wheel, don't get me wrong, but it goes down easily, is well written, captivating, interesting MCs, what more do you need?!

Will be recommending!

Das Buch „Twelve Dark Hours“ von Amber Hamilton umfasst 400 Seiten und ist bei Bloomsbury Publishing erschienen. Der Klappentext verspricht nicht zu viel: den Leser erwartet hier ein spannendes wie tödliches Abenteuer, das einen kaum zu Atem kommen lässt. Der Schauplatz ist grausam und das wird auch unverblümt so erzählt. Es ist der Autorin sehr gut gelungen, die verschiedenen Charaktere zu zeichnen und die Welt bzw. die Schule vorzustellen, ohne dass es gerade zu Beginn langweilig wird. Im Gegenteil, es geht spannend los und kontinuierlich atemberaubend weiter. Ich wollte ständig wissen, was als nächstes passiert und wurde immer wieder vom Verlauf der Handlung überrascht.
Ein schonungsloses Fantasy-Abenteuer, das zu fesseln weiß - ich werde mir diese Autorin merken!

“I am with you. In the Dark and in the Light. I’m with you.”

What an absolutely unhinged rollercoaster ride that was!

Due out in November, Twelve Dark Hours by Amber Hamilton is a standalone YA fantasy with gothic vibes and touches of horror 💀

The story follows Vesper and Lonan: academic rivals at Gossemort Academy, who are both hiding dangerous secrets. 

When a mysterious Prince sends the school into lockdown for a series of deadly trials known as ‘The Ridding’, there’s quite literally no escape, and the pair are forced to work together to face the horrors and survive til dawn ⏳

You can expect:

📈Fast pacing - with the descent into chaos and the clock ticking down, this book feels like a Cinderella-inspired nightmare that you can’t outrun. It’s action-packed the whole way through.

⚔️Deadly trials - this is a contest that no one signed up for, and some of the trials are seriously unhinged! The horror elements had me constantly wondering what fresh hell was up next (I never had to wait long!) and I’ll be forwarding Amber my therapy bill for the coffin scene.

💔Fated mates gone wrong - a great twist on a classic trope. What if your fated mate was actually a fate worse than death??

🩶Morally grey MMC - I was living for the snippets of Lonan’s POV - the yearning!!!

🧠Fragile male egos - “Whoever said there’s no fury like a woman scorned never saw the detonation of a man spurned by a woman.” CAN I GET AN AMEN?!

This was such a fun ride with a definite nightmare vibe! Highly recommend if you enjoy books that have your nervous system on high alert the whole way through.

Thank you so much to the author, NetGalley, and the publisher for this ARC!

Unfortunately, I was unable to read this book either on my phone kindle app or my actual kindle (amazon fire I believe) due to formatting errors - namely sentences being split across multiple lines. However, from what I did read, I really did enjoy it, so will be purchasing when it comes out so I can read it properly. I'm just sorry that I was unable to give a helpful review as I was unable to read it.

I felt like this book was written just for me, it hit the spot in every way a book should. I could not put it down and found myself telling myself just one more chapter!

This was a quick paced book where the action starts straight away keep the same pace throughout the whole book. this book has twist and turn throughout while students are faced with deadly trials.

I absolutely loved the MFC she came across as a badass who was determined and fearless and took multiple risks for the people she loved and didn't stop fighting throughout the book. I really enjoy the little snippets at the end of chapters from Lonan, I found that it really added an extra layer to the story and it was nice to see his feelings on the page! All the other characters brought something different to the story and I found that no two characters were the same.

This story did well to blend high-stake trials, nonstop action and horror with the immense world building to really make you feel a part of the story. I found that the plot had me guessing with some of the twists, while also having the romance that delivered plenty of moments that made my heart flutter.

I was lucky enough to receive an advanced readers copy of this book and leave my review voluntarily. it is the first book I have read by this author but it defiantly will not be the last.
