This book is a part of the zombie genre (of which I am a huge fan). In the story there are several different types of zombies, since they have the ability to mutate and evolve. The main character is fighting for his own survival when he becomes infected and ends up being a leader in a pack of zombies.
The first few chapters of the book was awful. I felt bored and confused, but I decided to go ahead and read the entire thing. I am glad I stuck with it, because it got a lot better. I started to relate with the main character and was able to really get into the story.
All and in all, I would recommend the book. I give it a B-
