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!

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.

great new book by a coming author read all his books

Andrew is one of my favorite authors, so I was very anxious to read his latest book.

It did not disappoint at all. It was deliciously twisted and disturbing, and made me feel like I was going crazy while trying to figure out what was happening.

I was excited to have the opportunity to obtain an Advanced Reader Copy (ARC) of this book from NetGalley.

Riley can’t remember the details of the tragedy that resulted in her breakdown and commitment. All she knows is that her life will never be the same again. Society believes she’s responsible and reporters hound her. She believes that even her sister harbors doubts about Riley’s involvement. After her release, Riley, armed only with her moxie and the mantra “Get out. Stay strong. Trust your truth.” tries to start a new life. The deck is stacked against her. No one wants to hire her. She becomes the victim of vandalism. Her new apartment, located in a sketchy part of town, feels unsafe.

Things look up once she spies her enigmatic neighbor Samantha Light, but soon Riley’s obsession with the woman and her charmed life threaten to drag her back into the darkness.

Riley’s character intrigued me, especially her friendship with Wendy, another neighbor. The cast was heavy with female characters, with only one memorable male character, Randall, an attendee at an art gallery opening. While I enjoyed the book, at times I had difficulties in suspending my disbelief to buy into some for the events of the story and in the ending. The author did a good job of parceling out information to create a suspenseful read.

Fans of stories with unreliable narrators and readers who like to be kept guessing should enjoy WHAT SHE DOESN’T KNOW.

There's something very depressing about this book. The good thing is that Girl on the Train also had a super depressing heroine and look how well that turned out!

There's also something very gray and/or dull about it. Like the weather outside, the streets, the buildings, the furniture, what people wear...their pasts. If someone was to make a movie based on this book, that would be their choice cinematography.

The pace is good, not too many descriptions and the dialogues sound realistic. However, the storyline itself didn't make me sit up in bed through the night just to find out how it ends. It's more of a light read that is occasionally putdownable (seems to be a popular word to categorize mystery books).

What an intense story and one that was difficult to put down. The twists and turns kept me turning the page till the very last sentence. The tragedies that Riley has experienced and the terror she feels seems so real. The ending was unexpected as I found myself believing in Riley. But who was the last victim?
