Beyond Black by Hilary MantelRead about the other entries on the list.
Mantel, best known for her Thomas Cromwell trilogy, is also one of the greatest chroniclers of the demonic going. Her earlier, devastating novel of a horribly traumatized, but quite authentic, psychic creates jet-black humor out of unspeakable horror. Mantel’s Alison Hart is plagued by the ghosts of her abusers, a chipper flock of grotesque spirits who discuss child-rape and sandwiches with precisely the same vapid bonhomie. The suggestion that Morris and his friends have, ah, graduated from being mere ghosts into something more hellish comes from the way that they answer to “old Nick.” “Nick he is a fambly man,” the ghouls explain, and Satan himself might cut very close to home.
