*2.5 stars round up*
The first 50% of this book had me hooked, I was invested in the characters and desperately wanted to know what was going on with the tenants of the "apartment. I was sadly disappointed with the last 50% of the book, with no real plot development and a flop of an ending. I felt like the author had something going but ultimately rushed through the most pivotal sections.

Thank you to Netgalley and Amazon Publishing UK for a chance to review this arc in exchange of an honest review.

Thank you Net Galley for a copy of this book. I loved the synopsis of the book and the cover reeled me right in - I’m a sucker for a good thriller and thought it would be a lot like Riley Sager’s Lock Every Door. The pacing was a little slower than I imagined and it began to feel like I’d never get to the middle of this story. The big twist was one that I wasn’t expecting but I somewhat feel like it was underwhelming. The plot was fragmented (was her foster care history and her marriage that important to the story?) but I know some people appreciate this type of thriller.

Thank you to the author, the publisher and enthralled for an ARC of this book for an honest review.

This book was easy to read, become a part of and it truly didn't end the way I thought it was going to. It did keep me on the edge of my seat and I truly enjoyed being able to relate to the characters and the story line itself.

I enjoyed this psychological thriller and the setting of the creepy, atmospheric Adder House Apartments. The one problem I had was it was soooo similar to Lock Every Door by Riley Sager.

The book also went a little off the rails for me too. It was so implausible.

Thank you to NetGalley for an advanced copy of the book for an unbiased review.

This thriller kept me reading to the last page. Some of the warnings of danger were a bit obvious (c’mon, this isn’t just a creepy coincidence!), but the narrator was likeable and the mystery was interesting and the writing was great.
*What* was being done to the narrator was obvious but who was doing it (& why!) kept me guessing till the end. I was afraid it was going to be a bit more horror than it ended up being, which is a good thing (I can’t stand a book with harm to children, and this book only hinted at it.)

4 stars because it wasn’t ANAZING, but was a solid fun thriller.
Thank you Netgalley and the publisher for the ARC.

Freya. and her young daughter, Skye find themselves without a place to settle down. Deceived by a cheating husband, who then died, Freya must sell their home and search for a new start.

At a coffee shop, she meets a man who offers an amazing apartment for a very low cost. Better yet, it's in an old mansion. Freya can't believe her luck, although the tenants there are all eerie or quirky.

Several times, we jump into the POV of an antagonist, and from this we know someone has been watching Freya and Skye, and knows quite a bit about them. We learn they are meant to be in Adder House but why?

There are also flashbacks to the early 1900's, and a mother and son's involvement in a cruel experiment testing out a child's reaction to fear. I felt like this was a weaker part of the story and could have been better incorporated.

Adder House has secrets, and is creepy for many reasons, all of which should have made Freya pack up and run after the first few occurrences. I enjoy a book with good introspection and this one did not disappoint. Perhaps in a few of the more fast-paced events, there could have been less.

I read this fast, wanting to know what was going on, who wanted them in Adder House, and why.

Others have said this, too: the ending was a bit rushed to wrap up all of the connections but overall, I enjoyed the book.
Thank you to NetGalley for the opportunity to review.

I do not agree with the negative reviews. This book was good. I liked the twists in the book & I am not sure what questions people feel were unanswered. Some areas were no 100% closed out in detail but that was not neccessary. The plot was unique & kept you guessing & changing your mind about characters. Quick read.

Psychological thriller as young single mother is offered an amazing apartment for her and her daughter in London. What it comes with is hard for her to figure out, but the drama builds as we see her fear grow. Being spied upon, strange rumors about what else happened in the apartment, and unusual happenings all lead to her terror. This is interspersed with 75 year old notes from a psychology experiment, that eventually yield the secret. The writing keeps the tension up on every page, with almost no letup.

This was my first KL Slater novel and it won't be the last. This apartment followed an out of luck mom who is about to lose her home. At the last second she is given an amazing opportunity to live in an BEAUTIFUL new apartment for free along with her daughter. At first, it is more than they could dream of. While it seems like it was too good to be true, Freya and her daughter take the apartment and are amazed at everything that it has to offer. Slowly but surely things start getting spooky. Are they in the apartment alone? Why does it feel like someone is always there with them? While I found that the plot was a story already told, I was mesmerized by KL Slater's take on this psychological thriller. This was a quick, in one sitting, read that had me gribbed from beginning to end. I did feel that the end was slightly fuzzy and didn't quite answer all of my questions, but it worked.

I was quite surprised in how good this book was the author had great storytelling and the characters built up was great as well. Would read more from this author.

As a fan of K.L Slater I was excited to read her newest book.
I found the story to be engaging and I wanted to know what was going to happen next however the switching of perspectives was confusing and I didn’t like how that aspect of the book was set out.
I liked how it wrapped up and it kept me guessing throughout, but I did think it was all a little rushed at the end and could have expanded more?

Loved this book.
Was a great read from the very start.
Some parts of it were really upsetting but overall it had great back stories and most of the characters were really likeable even though you wouldn't have thought you should like them. Book was very well written and very descriptive.

This was an incredible book. It was a completely different book and had twist and turns until the final end. I enjoyed the main characters and stayed up into the night to finish the book. Another great read by this author.

She’s offered an amazing apartment in a wonderful location for an amazing price just when she needs it most. But, if it sounds too good to be true, then run! Freya doesn’t run and instead is drawn into the secrets of Adder House.

I enjoyed the book for the most part. It was a unique story. It’s biggest downfalls were it read a bit flat and there wasn’t enough suspense built up.

An interesting book. I got all the way through, but would not recommend this novel. Without spoiling the twist, the book relies on some historical occurrences that are rather silly in the context of this particular mystery, and don’t make sense either from the perspective of the villain or from the plot.

A great and, at times, uncomfortable read about a woman, Freya who having lost her husband and her home finally gets a break when she is approached in a coffee shop with an offer she cannot refuse of an amazing apartment at Adder House for her and her daughter. They move in the following week and Freya can't quite believe her luck but then strange and unexplainable things start to happen. She also starts to hear rumours of something horrible happening at Adder House so she decides to find out what.

I devoured this book in 2 days. I just had to know what happened next! I absolutely loved this book. Very well written, engaging and fast paced. I could not put it down! Nice short paragraphs also which I always like.

I would recommend if you want a book this is going to entertain you and keep you guessing!

Love love love this author and yet again she has given us a superb read. It certainly brings home that old adage, it it seems too good to be true, it probably is! The book had me gripped from the first page and I read it in one sitting. It entertained and thrilled in equal measures and the twist at the end was brilliant. I look forward to Ms Slater's next offering.

This book was very entertaining , well written . It took me a little while to get into the story line but I am glad I continued to read because I couldn't put it down .

- little to nothing happens for about 90% of the book.. honestly felt like I was reading a contemporary at some points
- this could have gone so much darker and been so much creepier but nope
- ending & epilogue was a big fat womp from me. so many questions still left unanswered, so little explained, and nothing really felt shocking or surprising. the epilogue felt like something out of a romance novel for whatever reason.
- the chapters we get from the "villain" just felt out of place and not genuine

The story, a psychological thriller, has some interesting moments, but the telling of it is uneven - sometimes rushed, sometimes too drawn out. It's a quick read, but had to many tropes, and was a bit too predictable for me. Freya was very wishy washy, and seemed more a "stock character" than a real protagonist.
