I could not put this book down! I am a fan of both of these authors so when I saw that they partnered up to author this book I knew I would need to read it and they did not disappoint me at all. I was hooked from the very beginning and stayed up way too late reading this. If you like a psychological thriller that's full of twists and turns and keeps you guessing then you won't want to miss this book. This is one of those books that stuck with me when I wasn't reading it. I just could not stop thinking about the characters and what would happen next! I kept trying to guess what would happen next and how things would end, of course, I was wrong about everything. This was a very quick, fun, and unpredictable read!
