This book takes place in London, and pretty much everyone 16 or older gets sick. They get a cough, a runny nose, and boils. Light bothers them and the voices in their head tell them to eat the kids. They turn into zombies (although the characters in the book make a point of calling them "sickos" because zombies are undead and the sick people aren't). The kids are left to fend for themselves in a world with no adults. Food is hard to come by, and whenever anyone goes out, they are attacked by the zombies. The book follows one group of kids, and every once in a while, the author kills one of them.
It wasn't a very good book. It was a bit too bizarre. There was one kid, Matt, who was convinced that he had seen "the Lamb of God," and whenever something happened, it was meant to be. He was really annoying. It wasn't very well written. The book never seemed to go anywhere, and nothing really developed. A new kid would come, and a different kid would die, so none of the characters had time to develop. It didn't pull me in, and I did not find it particularly enjoyable. And it had a bad ending.
It gets a 2.
