You know that you read wayyyyyy too many thriller novels when you predict a much better ending than these two co-authors came up with together! That being said, I still feel that the book was pretty good and very well written, definitely different, very fast-paced and I would recommend it to my fellow thriller lovers! I believe this is a debut novel too--so it can only get better from here on out!! My twisted Lil thriller obsessed mind could've done more with that ending though... haha! I also think that reading AJ Finn's " woman in the window" may have changed my mind a bit since I read both books the same week and Finn kept me on the edge of my seat whereas this one did not. Thriller genre is my favorite genre so I'm a pretty harsh critic!
