The reason I love this book so much is because it doesn't feel like fiction at all, which makes it all the more terrifying. The narrator is a journalist who travels the world and interviews people on the early days when zombies were first discovered, the war itself, and the aftermath. The book is basically divided into these three sections, and has a very matter-of-fact voice. It is basically told through the eyes of the survivors, and has varying levels of anger and reflection by the interviewees, and almost none by the interviewer.
This book is not for the faint of heart or people who can't handle bloodshed and violence. I would not recommend it to younger readers. I do recommend it to anyone who like zombies or war stories.
