Zombies are just one of my least favorite supernatural creatures ever — I know that they're supposed to represent the triumph of the id and also the otherness that people feel to the vast enormity of the world/culture today, but give me a nice, evil, intelligent, strategically thinking (non-sparkly, please) vampire or fallen angel who's got a brain and supernatural powers to augment it any day.
That said! We have a book that came out a week and a half ago called Brain Camp, and it takes the other side of this fear-of-zombies thing. It's not so much about avoiding the not-very-swift-running zombies as it is the fear of zombieism, that what makes you yourself will be taken away by powers/circumstances beyond your control.
Also there is summer camp, which is just terrifying in and of itself.
Don't you want to have them come visit your schools and/or library? They will promise to keep their eating-of-brains to a minimum.
Do you really need all those students?
