The Graveyard Book | Neil Gaiman

It takes a graveyard to raise a child. Nobody Owens, known as Bod, is a normal boy. He would be completely normal if he didn't live in a graveyard, being raised by ghosts, with a guardian who belongs to neither the world of the living nor the dead. There are adventures in the graveyard for a boy--an ancient Indigo Man, a gateway to the abandoned city of ghouls, the strange and terrible Sleer. But if Bod leaves the graveyard, he will be in danger from the man Jack--who has already killed Bod's family.
