Welcome to the city of the dead...When Hoole, Tash and Zak stop at the Necropolis to find a new ship, Zak immediately makes friends among the local kids. And he decides to do something crazy - he goes to the necropolis cemetery at night just to prove that he is as tough as they are. The cemetery is as quiet as a grave, full of white, wriggling bone-eating worms. Perhaps Zach should have thought twice before taking on this challenge. Just because bodies are buried doesn't mean they're dead...
