Initially, I didn't think I would like this book. The point of view was irritating because you are going from head to head. You are listening to all these people and it happens from one paragraph to the next. It was insane for a bit. Technically, it is considered bad writing to do that but.... for this book it was probably a brilliant choice.
I think it is this choice of POV that gives the frenetic pace to the story. There is a sense from the beginning that the main character is having some major mental problems. Something is just off kilter in his behavior and it only worsens. I found myself sympathizing with everyone he came in contact with, even the most reprehensible characters in the story, and I was scared he was going to kill any one of them. Because I just knew the main character was going to hurt someone. The action escalates pretty quickly and after a few chapters, I was hooked and on the edge of my seat. I couldn't put it down but had to in order to give my nerves a break.
I was relieved when I finished the book but not disappointed. Just when I thought it was over, there was a twist in the finally I didn't see coming but which I found satisfying.
