I really enjoyed this book. I read it in 1 day! That being said, it did drag in the middle so I couldn’t give it a 5. It is a great psychological mystery and part of the mystery is figuring out who to trust. Sometimes I hated the main character but I finished the book loving her! She develops into an amazing woman (I am not using names because that would ruin part of the story) I was pleasently surprised by the many twists the story took. Some I expected but many more totally shocked me. I loved how the authors followed through on every story line so you understood the many nuances of the story. This book will make you question your relationships and wonder about your friends relationships.
