The Graveyard Book by Neil Gaiman

Bod is an unusual boy who inhabits an unusual place—he's the only living resident of a graveyard. Raised from infancy by the ghosts, werewolves, and other cemetery denizens, Bod has learned the antiquated customs of his guardians' time as well as their ghostly teachings—such as the ability to Fade so mere mortals cannot see him.
Can a boy raised by ghosts face the wonders and terrors of the worlds of both the living and the dead? And then there are being such as ghouls that aren't really one thing or the other. (Description from Amazon.com)
