This book was quite dark, with twists & turns throughout. Some parts were predictable, other parts caught me off guard and I did find it slow in some parts hence the low star review.
All in all it was a decent read, I just wish it was a bit more faster paced. Don't let my review put you off though, because you may really enjoy this one.

This felt like a very topic read, young boys getting sucked into things they see on the dark web and their misogynist views towards women.

A difficult and dark read at some points. It wasn't an easy read.

Thanks to netgalley for the opportunity to review this book, this is my honest opinion.

The Tree House by B.P Walter
⭐ ⭐⭐

What would you do if something you did 20 years ago comes back to haunt you, in the form of a TV Series.
Well brothers Robert and Kieran are about to find out.

Initially going into the book I was looking forward to a thriller that had me gripped from the very beginning. The plot of this book was intriguing and was the reason I wanted to pick it up the second I got my copy. Unfortunately for me the book was very slow to get going, this could be down to the writing style or longer length chapters.

I didn't see the twist at the end coming and I really like when a thriller does that. However I did find it to miss the mark a little on being called a thriller.

I like when a book jumps from present to past meaning you get to experience the story building. This book did need to have some parts condensing down to make it flow more. Again this could just be the writing style

Overall I enjoyed this one in places, especially the plot twist. I definitely think this would appeal to people who like a more in-depth thriller book.

Thank you to @Netgalley, @onemorechapter and @harpercollins for a Copy of The Tree House, in return of a honest review

I think dark and creepy best describes The Treehouse.
Interesting storyline if a little far fetched.
What a family!!
The only parts i struggled with was the animal cruelty which i had to skip through.
My thanks to netgalley and the publisher for my copy.

I very much thoroughly enjoyed this book. It was a quick read, twisty, and “unputdownable”. This was my first book by this author and it will not be the last!

I honestly think it's criminal how underrated BP Walter is. This is such a dark, twisty thriller with a knockout ending. I flew through this one and you will too

hank you, HarperCollins UK, One More Chapter, for providing the copy of The Treehouse by B. P. Walter. I loved the premise, but the story itself was implausible. The Dark Core made no sense to me, and it was never explained why people were so drawn to it. I loved the idea of the TV show that had supposedly mirrored the past events, but it wasn’t handled or conveyed very well. The long stretch of the past timeline wasn’t interesting at all to me, and I kept waiting for the parents to explain what they knew/had done. Readers who love a surprise reveal will love this book, but I needed more substance and to be able to believe in the characters and events! 2.5 stars rounded up to 3.

⭐️⭐️⭐️⭐️⭐️ 5 stars!

The Treehouse is a dark, twisty gem of a book. At times I was almost as anxious as Robert that everything was about to fall apart for him. Just when you think you have this story figured out, another twist will prove you were way off track.

This book will appeal to anyone who loves read it in a weekend page turners and dark flashback filled mysteries like Donna Tartt’s “The Secret History”.

Thank you to NetGalley and One More Chapter for the opportunity to read this ARC.

(slight spoiler)
This depraved I Know What You Did Last Summer meets MidSommar was so scary I physically jumped when the doorbell rang while I was reading it.
The tone and pace are so intense I was scrolling quickly to find out how everything resolved.
It started off so good, but at the last 20% the twists were so unbelievable-almost silly- and unnecessary that it brought down the rating from 4 to 3 stars. Many thrillers nowadays are now adding so many twists and extra accomplices and it rarely works.
Thank you HarperCollinsUK and NetGalley for the digital review copy.

I was a bit put off at the outset by the opening scene of the novel - two boys engaged in the murder of a girl in the eponymous treehouse. I'm so sick of it always being women and girls whose deaths are served up as entertainment.

I did like the hook of a TV series called The Treehouse inexplicably - because no-one was supposed to know about it - telling the story of Chloe's murder twenty years later, much to the alarm of the brothers involved, Kieran and Robert. That was intriguingly mysterious - how on earth could their story, never spoken of, now be on screen? The mystery is disposed of fairly quickly, though, and we go back in time to see how the two then-teenage boys came to do something so awful.

It's all a bit far-fetched. And I don't believe something like the Dark Core movement which the boys get mixed up in could exist without the media getting wind of it, not when they're sacrificing rabbits all over the internet. I can just imagine what the Daily Mail would have to say about it all.

The whole Dark Core thing has a strong whiff of ridiculousness, it's so over the top. But I suppose I can imagine a certain type of teenage boy being enthused. They like Andrew Tate, after all. Things go pretty far here though.

It's a readable story, but I didn't really like any of the characters - poor old Chloe was probably the best - and by the end all the twists are getting a bit much. ("I'm guilty... No you're not, I am! Haha, no, it was actually ME!" etc.)

Thanks for the opportunity to read and review. The story did keep my interest, but ultimately wasn't really for me.

Kieran and Robert committed an atrocious act 20 years ago and a tv show has reenacted it in a fictional setting. This is impossible because they are the only ones who know what they did, or are they? This was crazy. Whether it was too crazy is debatable. I do wish the structure of the book was a little different since we spent like 15 chapters in a row in 2004. Thank you NetGalley for the ARC. 3.5 stars.

Review of ‘The Treehouse’ by B.P. Walter due to be published on 3 July 2025 by Harper Collins UK, One More Chapter.

The story follows two brothers, Kieran and his younger sibling, Robert, who are shocked when a TV show airs, named ‘The Treehouse’ which claims to be a work of fiction - however, the storyline echoes events they do not speak about that happened 20 years previously.

In a frenzied panic, Robert seeks to find out the truth, which leads to another chain of events, deepening the mystery and truth of what happened all those years ago.

The book has several chapters set back in 2004 when the main events took place, which tied in nicely with the present day storyline.

There are some dark scenes depicted in the storyline, but all are relevant to gain an insight into the minds of the protagonists.

I’ve no doubt that this will be another bestseller for B.P. Walter!

This was such a good book. I loved the story and the writing so much. The characters were great and the story flowed smoothly. Will definitely read more books by this author in the future.

This is a great thriller - gruesome, shocking, horrifying, exciting and darkly funny. I had to laugh at some of the plot twists, they were unexpected and yet somehow predictable. What a delightful family!! Great characters and a cracking good plot. I wouldn't rush to read more of this author, though.

The Treehouse is about two brothers who develop some rather dark interests as teenagers, and how these obsessions affect their lives moving forward for the next twenty years. There is animal cruelty on and off-page, and this was a stressful read for me as I fought to get through it. There are also major issues with pacing - we jump back in time for twelve straight chapters or something like that. The ending felt like an attempt to shoehorn in as many twists as possible into the final forty pages. I appreciate what the author was trying to do, as well as the chance to read this early, but overall I just did not care for it.

While I understand this entire book is based around a cult type thing and a sacrifice, I did not enjoy the chapters that talked about this. The research. The act itself. Those chapters I skimmed. The chapters set in present time, I really liked.

Kieran and Robert killed a girl when they were teenagers. Now years later, there is a show made about this exact situation. But no one knows what happened so how can this be? Started out good. Didn’t enjoy it by mid way.

Stayed up late to Read this in a night, I really enjoyed this book. I would read more books by this author

Thank you Netgalley and the publisher for this arc. I enjoyed this one. Although I didn’t really connect with any of the character, there were so many twist and turns that I enjoyed the book anyway! Not my fave by this author but still a book I’d recommend

It was brilliantly paced from the very first page, I found myself engrossed in the read! I had to remember to breathe, it was so gripping! UNPUTDOWNABLE!!

I read a lot and very critical! I can figure out the twists from almost the start, but not this book you will love this book!


I absolutely LOVED it!! It kept me on my toes the whole time and instantly grabbed my attention. It's definitely a must read!!

I loved all of BP Walters book and this one is no different, I think this is one of the best books I have read in a long time.. The Palmer family are so toxic and their story is dark and twisty. I cannot wait for more from this amazing writer.
