Man oh man. Where do I even start with this book?? I love psychological thrillers so this book was right up my alley. If you enjoy psychological thrillers as well and you have not read this one, then you need to put this one on your list right now!! This book had me guessing what was going to happen the whole way through. There were times I thought I had it figured out, but boy was I wrong. I really started feeling bad for Jess during her “study on ethics and morality” experiment she does with Dr. Shields. Jess gets put in some really bad situations and you start wondering why Dr. Shields would let this continue on. Plus through in some unreliable narrators and this will keep you on your toes the whole time. Then you get into the stuff with Dr. Shields husband and you have no idea who to trust. I love a book that can keep my attention and keep me guessing, and this book does both. Very entertaining and I highly recommend this to my fellow thriller lovers out there.
