When he tells his story to the police everyone thinks he's gone mad, that he's imagined the whole thing, and lock him up for being insane. His uncle Dervish visits him in prison and gradually reveals the curse hanging over his family -- as well as the reason why they're all obsessed with playing chess!This is a much more horrifying, hair-raising, fast-paced story than any of the Darren Shan books or any of the horror stories you've read before. It's gory, full of very real demons and werewolves -- and guaranteed to give you nightmares!
