This was a fully absorbing thriller. I could not put this book down, constantly wanting to know what would happen next. Every part of this book was a twist and had you second guessing everything as you read it. Way to go Alex Michealides on this fantastic debut novel. This was a very fast read and the ending had me saying what in the actual, what just happened? I definitely did not see that twist coming which is the best part of a good thriller. Normally I can pick up on things through out a story and figure out the who done it before the books ends but, this one blew me away. I loved this writing style, and I really enjoyed the setting of it being in the mental hospital. I am really looking forward to reading the next book Alex comes out with as it will a for sure be a one click buy for me.
