Neil Gaiman and Dave McKean - The Wolves in the Walls
The Wolves in the Walls is a phantasmagoric story written by Neil Gaiman and illustrated by Dave McKean.
Truth be told, Neil Gaiman and Dave McKean's picture book The Wolves in the Walls is terrifying. Sure, the story is fairytale-like and presented in a jaunty, casually nonsensical way, but it is absolutely the stuff of nightmares. Lucy hears wolves hustling, bustling, crinkling, and crackling in the walls of the old house where her family lives, but no one believes her. Her mother says it's mice, her brother says bats, and her father says what everyone seems to say, "If the wolves come out of the walls, it's all over." Lucy remains convinced, as is her beloved pig-puppet, and her worst fears are confirmed when the wolves actually do come out of the walls
