The Great Ghost Rescue

Audible Audiobook (Pan Macmillan Publishers Ltd. July 9, 2008)
As a bloodcurlingly fearsome ghost, Humphrey the Horrible is a failure. He's not horrible at all. Instead of being ghastly and skeletal, he's pink and fluffy, like a summer cloud. He longs to be like his brother, who's a Screaming Skull, or his father, who has stumps for legs and a sword through his chest...or even his cousins who are like vampire bats. Poor Humphrey, though, can't scare anyone.

But when the ghosts are in danger, it's clever Humphrey who comes up with a rescue plan.
