I don't know if I've ever fallen into a "world" of a book like this one. With the vivid descriptions of things like a gunshot or the way a hitman feels when he wakes up in the morning though, you can't really help yourself.
This book has a world of its own that is very gruesome and at the same time oddly humane. You get to watch the characters learn more about themselves and essentially change through the violence in which they all live.
The twists and turns of the story are unexpected but believable and the story itself was realistic. For Nothing is really a great book all around. I thoroughly enjoyed it.
