This is a psychological thriller that keeps you on the edge of your seat. You will never be able to see the ending coming. Riley is released from the mental health hospital after treatments. She was a prime suspect in her daughters murder over ten years prior. The case was dropped as their was no solid evidence that she did or did not murder her daughter.

Upon her release she begins slightly stalking her beautiful neighbor. In a twist her neighbor is actually the one stalking her and has incredibly violent tendencies.

Make sure you read this you won’t want to miss out!

3.5 stars rounded up.
When we first meet Riley it is as she is being released from a psychiatric facility. Picked up by her sister, she is taken to her new home. The reason for her incarceration is that she suffered a breakdown after the murder of her daughter. A crime that has not been solved. A crime she has little memory of. A crime that she herself was accused of. With no resolution, she fears her freedom. With the finger still pointing at her, even after all the years gone by, will she forever be labelled a child killer. Slowly she starts to try and put the past behind her, to try and scrape out some kind of future for herself. But it becomes all too clear that this is to be an uphill task when she appears to be being targeted. Is someone out to get her? But then she becomes obsessed with one of her neighbours. She contrives a meeting and then goes on to forge a friendship with Samantha. But then that relationship starts to go sour. In a spectacular way. Has Riley bitten off more than she can chew and will it all come back to bite her?
I really loved Twisted when I read it a few years ago so I was really excited to get my hands on this one. This book was ticking along quite nicely for the majority but, at the end of the day, when it was racing towards the final conclusion, it just didn't quite match up quality wise. It started off well, scene setting, character defining, drip feeding in little incidents to question what was going on, slowly ramping up the action and intrigue. Giving me as a reader some small breadcrumbs for me to make some guesses along the way as to what was the truth of what happened all those years ago and indeed what was happening in the present. But then, suddenly it felt like the book went a bit out of control. There were certain curve balls thrown in that just made the story judder rather than flow and I couldn't help feeling that the ending was a little rushed and not quite handled as well as it could have been. It's like the author had reached the end of a deadline and sacrificed plot and quality for delivery. There were also quite a few things that didn't quite make sense for me and that meant that I had to revisit previously read parts and that also ruined the flow of the book somewhat.
Characterisation was also a little strange for me. Yes, I get that in this genre of book sometimes the characters are not as first defined. There are always going to be secrets, lies and duplicitous behaviour, it goes with the territory but here, they just didn't seem to quite work for me. There was a little too much about facing and polar opposite swings for me to believe in or connect to some of the key characters properly and this did mar my enjoyment a bit. What I did like however was the relationship between Riley and her sister. I found that to be very well portrayed and wholly believable.
Why have I rounded up my rating rather than down? Well, to be honest, the main story was good. the premise was sound. It just fell apart in the execution a bit. Yes it is only worth 3.5 stars on my scale, it definitely isn't worthy of just the three and, as neither Amazon nor Goodreads allow half stars, I have to go one way. And the fact that I finished the book without wanting to keep putting it down, and was mostly satisfied at the ending, my niggles may be high in number but low in severity, so I rounded up.
My thanks go to the Publisher and Netgalley for the chance to read this book.

This book will definitely keep you on the edge of your seat. I was obsessed with finding out what happened and could not put it down until the end. But by then it was too late.. was questioning my own sanity.

Rating: 2.5/5.0

This was a disappointing reading. I expected a lot after reading the synopsis. The story was very very slow. Sometimes I love slow thrillers provided there is some sort of event carrying the story forward is happening. up to 60 - 70% of the book the same slow rhythm was still going on and after that whatever twists or thrills happened I did not care for them because I was already bored and found my time got wasted reading into this.

The story is basically about Riley who is now out of a psychiatric facility where she was put in after being a suspect in a murder case. After being out she wants to have a new start but her new neighbor gets her interest.

This sounded interesting to me, but it did not translate to a fun thrilling book. I would say skip it.
I have chosen this book when it was available in the read now section of NetGalley.

I really enjoyed this book and it definitely kept me turning the pages. However, towards the end I found myself thinking more than once that the story was getting a little bit ridiculous and out of hand. I like my books to be somewhat believable and this just got to the point where it wasn't. It seemed soap-operaish in a way. I really liked the plot and the progression of the story until the end. I love a twist but it was just TOO much of one for me (never thought I'd say that!) I would still recommend it the read, just expect it to get a little dramatic at the end.

I received a copy of this book thanks to the publisher via NetGalley in exchange for an honest review. Thanks for the opportunity!

This has an interesting concept with a potentially sympathetic character in Riley but for me, at least, it would have benefited from a strong final edit to pull some things apart and others together. It's a fast read (short chapters) but I didn't find it as compelling as I'd hoped. Thanks to Netgalley for the ARC.

On the cover we see Riley Harper, his face is split. She was interned in Glendale Psychiatric center ten years ago almost for being suspected of murder and this destroyed her life. Locked up during all her years it is done that she is guilty in the eyes of everyone of or the journalist's obsession to interrogate him. Once she's released, she wants a fresh start away from all this. She's going to be obsessed with her new neighbor Samantha Light.

A good psychological thriller that leaves us in turmoil from start to finish, I highly recommend it.

This is the type of book I enjoy. I enjoy trying to figure out is the character really mentally unstable, did she or did she not do what she was accused of. This is a psychological thriller with many twists and turns in it. Riley was trying to get her life back on track after coming out of the mental institution and she encountered people who weren't good for her life and her mind. I found this book fast paced and a real page turner. It had quite the ending, I didn't see that one coming. Thank you to Thomas Mercer and Net Galley for the complimentary copy, all opinions are my own.

This book kept me guessing till the very end. Definite page turner!!!

I really loved this book! Excellent story with brilliant main characters. I would recommend this book.

Out of the gate, from the first few chapters, I knew this would not get a rave review from me.

After having read Girl on the Train - and been one of the few who did not enjoy it - I could see the similarities brewing between it and What She Doesn't Know. Riley, the main character, has just been released from a mental institution, having been accused of the murder of her husband and daughter. She is out in society, living in a world where everyone thinks she is guilty.

The reason this fell a little flat for me is that I am tired of 'unstable woman' syndrome. More and more books these days have main characters that seem unstable to those around them and so their mental state is questioned throughout the story. Did they see/hear/do THAT? Or was it all in their head? For that reason alone, this book did not receive top stars from me. The ending comes on quickly, a little too much so, but you may or may not see it coming. Riley's sister Erin is your typical over-protective sister character, not believing Riley and overly questioning her for the simplest of plot points. Trying to set the scene for readers? Or just her character?

While I didn't absolutely love this book, it did keep me reading to find out the ending. So thank you to Netgalley for providing me with a copy of this book in exchange for my honest review.

This book was provided to me by NetGalley in exchange for a review. Don't want to give a thing away. Read this book. Now!! SO great! You won't be able to put it down!

I was sucked into this book. So many questions that begged for answers. I kept guessing if Riley had totally lost her mind but there were events/people that kept dismissing that possibility. I flip flopped through the entire book. The 'not knowing' is what I like about mysteries.

While reading this, I was hovering around three stars. I didn't love it, but it certainly kept me reading. However, the more I read, the more frustrated I got.

I had issues with the writing style. I actually love present tense, which not many people do, so that wasn't what tripped me up. It just didn't feel as polished as it should have been. There's a lot of info-dumping. The dialogue is unrealistic at times. Every time Riley yells, it's in all-caps. There's no real setting of scenes, just sentences like: "It's been a few days since Riley left her sister that apology message and still no response." But every chapter (and each scene is a new chapter) opens similarly. A lot of the moments that should be emotional don't land, such as: "She applies the makeup, but even that can't fix the damage caused by a life wasted, a life destroyed. Then a tear--the kind that expresses what words never could--rolls down her cheek."

Overall, the story felt very surface-level. Kaufman told me what was happening, but I never felt the characters like I should have. Because of this, everyone comes off very one-note. I should be sympathizing with Riley, but I'm not because I know she's holding back info. I'm interested in mystery/thriller stories, but I'm reaching the saturation point for unreliable narrators. That, or Gillian Flynn did it so well that she spoiled me.

As the story goes on, I mentally downgraded this from three to two stars because it was getting outlandish. All I wanted was to figure out what was actually going on. I would've stopped taking away stars there if not for the ending. I think Kaufman tried so hard to make the story surprising that he instead falls back on the cheapest ending. When you have a female main character who's questioning reality, I think it's dangerous to try to make readers empathize with her only to pull the "No, she's actually crazy" card. That's an irresponsible message. Mental health is a tricky issue, one a lot of people struggle with, myself included. This book falls squarely in the category of suggesting that mentally ill people are dangerous to other people while the majority are not. In a time of rampant public violence, I don't think that's the side of history authors want to be on.

I don't enjoy giving books low ratings, and I don't mean anything by it beyond this book wasn't for me. Although I can't recommend this personally, I see a lot of people have enjoyed it. If mysteries are your thing, you might want to check it out.

If you want a psychological thriller, THIS IS THE BOOK!!!! This book had me from page 1 until the end. I could not put this book down. I love that the chapters were short, it was a fast paced book. Lots of twists and turns throughout. Kept me guessing til the end. Whoa! What an ending!!!! This is my first Andrew Kaufman book but will not be my last. Much thanks for this complimentary copy of this book from Thomas & Mercer through NetGalley. Opinions expressed in this review are completely my own.

Ehhhh I just couldn't get into it. I liked it well enough when reading it, but when I was not reading it I avoided it like an ex boyfriend in target.

This is not just another Psychological Suspense Story voiced by an unreliable narrator, this book has an ending that is quite different and one that most won’t see coming. If you think this story is a bit predictable and you have it all figured out early on, guess again! Fast paced and chilling this is a very good read! Well done, Mr. Kaufman!

I've read a lot of thrillers before. but this one frustrated me to no end. There's no doubt that  Kaufman is a talented writer, but the novel feels like a bunch of ideas thrown together without any real thought to how it's going to turn out. The plot seems pretty straight forward, but the thing is by the middle of the book you begin to wonder why this is all happening. Sure, we all like plot twists, but this just left me scratching my head wondering how no one saw any of this coming. Let's be honest here and admit that it's kind of clever, but it couldn't really happen. How in the hell didn't anyone see any of this happening? Riley's sister is pretty much useless here, and Riley is pretty sketchy as a lead character which shouldn't really surprise us. It's not the story that frustrated me. it's the ending that left me practically throwing my Kindle across the room.

      The truth is, I really liked this book, I did, but Kaufman's story slowly begins to unravel with the addition of Samantha. A lot of these books do have a few twists and turns which is why we keep reading them, but none of these characters seemed to have anything likable about them. You should at least have a lead character you like, and root for, but Riley is just boring, and not enough is told about her daughter's death to make us feel anything remotely like sympathy. Of course Samantha is a main part of the second half and she's an interesting character, but I would have liked to see more of her. When it's all explained it doesn't seem to have any weight. There is so much potential here, but I just couldn't get into this at all. I'm sure there are readers who will call me insane because I felt that the book was lacking something. There are pieces of other stories here in better books that have had a way bigger impact than this one did.

After reading it there was a bit of shock as it all began to settle in. The ending is built to surprise you, but to me it didn't make a whole lot of sense because you kind of expected it to end the way it did. Given what Riley has gone through and the subtle clues throughout the novel, it's not much of a surprise ending. As I guessed in the first few pages what would happen, and I was sort of right. In terms of pacing, Kaufman does a pretty good job of moving the story along even when the novel slowly goes off the rails. There's a lot of potential here for a great novel, yet to me it just felt okay. If anything, it's a pretty decent B, or C level thriller. You read it. and promptly forget about it.

Riley Harper is not living a life that anyone would envy. She lost her husband, her daughter, and her mind. Though not convicted, public opinion is against her and many believe her guilty of a horrific crime. When she is released from a mental institution, the press hound her, her apartment is compromised, getting a job may not be possible and her sister, Erin, the only person she has left in her life questions her innocence. If Riley knows what happened to her daughter, she isn't saying and she swears she has no recollection regarding how her daughter died. If that isn't enough to make your head spin(mine certainly did), she also becomes obsessed with her neighbor. Samantha Light is young, beautiful and seems to have a perfect life, in short, she has everything while Riley has nothing. There were so many twists and turns and every time I thought I had a handle on what was really going on with Riley, the author veered off in another direction.
The chapters just flew and this fast-paced thriller kept me guessing until the very end. Riley was an unforgettable character and all I can say is wow, what an ending. This is the first book I read by Andrew E. Kaufman and I imagine it will not be my last. If you enjoy psychological thrillers with an unreliable narrator, I recommend What She Doesn't Know.
Thank you, Andrew E. Kaufman, Thomas & Mercer and NetGalley for the complimentary digital edition to read and review.

Thank you to Netgalley and Thomas Mercer for an advanced copy of What She Doesn’t Know in exchange for an honest review.

Riley has recently been released from a institution after she was not found guilty of her daughter’s murder. Only having her sister Erin, Riley moves into an apartment. Slowly she becomes obsessed with the neighbor across the parking lot, while receiving threats and dealing with apartment break-ins.

Kaufman keeps the pace fast and the chapters short. With numerous twists and plot points that make you reread to make sure you have straight or read right, this book kept me wanting to get to the end. I wanted to know the final twist because you knew there would be one.
