There's nothing normal about Uncle Chunk. He's eccentric, unpredictable, and full of deep dark secrets. So why is he turning up at Billy's house when he hasn't been seen for years? Has he just popped in, or is there more to this mystery than meets a were-dragon's eye? And that's not the only thing Billy's got to worry about. Miss Hicks the werewolf has returned to school and his nemesis Scratchhook is watching his every move. Could this be the end of Billy the dragon?
