Honestly, I would not have read this book had it not been written by Krysten Ritter. I have been a fan of her work and thought I'd give her book a try. I was not disappointed. For a psychological suspense thriller it was really good. At first, I was reminded of Megan Abbot and her awesome book Fever, but this became less about teenaged mean girls and more about really messed up adults. The characters were all very well written. Our hero, Abby, is a refreshing departure from the usual damaged woman so often placed in psychological thrillers. Her damaged is undeniable and yet she doesn't use it to seek revenge or manipulate, Abby is self destructive and does really stupid things while trying to come to grips with her past in a way which is all too familiar and relatable. The mystery unfolds in sometimes unclear ways and the end does become a little predictable. I do hope that Ritter continues to create more female protagonists who defy stereotypes.
