The Cemetery Book | Neil Gaiman

No one owns, known as "Bud", born ordinary. But he is not completely ordinary, as he lives in a cemetery, raised by ghosts, guarded by a creature of a kind that does not belong to the world of the living or the world of the dead. "Bud" learned the abandoned customs of ghosts in the cemetery, and also learned their ghostly skills, for example: he can disappear completely so that the living do not see him. But if "Bud" leaves the cemetery, he will become vulnerable to danger at the hands of the man called "Jack", who has already killed "Bud"'s family. Can a boy raised by ghosts face the wonders and horrors of the worlds of the living and the dead?
