The Dead (Enemy #2) by Charlie Higson
THE DEAD begins one year before the action in THE ENEMY, just after the Disaster. A terrible disease has struck everyone over the age of sixteen, leaving them either dead or a decomposing, flesh-eating creature. The action starts in a boarding school just outside London where all the teachers have turned into zombies. Together they begin a terrifying journey to find safety, and home.
4 out of 5 stars. Lots of good action but it was pretty predictable. I was never really worried that the kids wouldn't make it and you never really got to know any of the main characters. They played a bit flat for me.
