For thrills and plot twists 5 out of 5, I docked it one star overall because I disliked the unreliable narrator (although she did keep things interesting). This book was definitely worthy of the hype surrounding it. I hate comparing it to Gone Girl and The Girl in the Train but...... I have to!! We have an unreliable female narrator who drinks too much, plot twists out the ass, and some dark hidden bits about her past. All intriguing! Basically a 38 year old woman who is "separated" from her husband has shut herself in her large New York City house for the past 10 months. After some mysterious traumatic experience (which the reader is dying to know all about!) she became a hardcore agoraphobic and can't leave the house without having a full fledged panic attack. She passes time watching classic noir movies, playing virtual chess and spying on her neighbors. When a new family moves in something seems off but then when she witnesses a crime in their house, no one believes. She's not making it up... or is she? Definitely unique and worth a read. I sped read this in one day.
