This is a 4.5 rating for me. This is really my first dip into the mystery/thriller genre outside of young adult, and I was not disappointed. I'm still left with curious feelings about Jacob. I went back and forth so many times on if I thought he was guilty or not. (view spoiler)[ Even now, it's pretty obvious that he was, but I still have a little doubt there. I don't know, I just always hope for the best in people, and I'm a bit naive I guess lol. I had a lot of problems with Laurie throughout this whole thing. And the fact that she killed Jacob in the end was not something that I had seen coming, but it really helped me to feel justified in my negative feelings for her. Jacob may have been a murderer himself, but I think there were a lot of mental things that had a play in that (hide spoiler)] 
 I was really concerned that I was going to be bored with this, since this isn't a genre that I lean towards, but I was pleasantly surprised. Both by the plot twists and my enjoyment.
