There is something strange about Coraline's new home. It's not the fog, nor the cat that always seems to be watching, or the signs of danger that Miss Spink and Miss Forcible, her new neighbors, read in the tea leaves. It's the other house - the one behind the old door in the living room. Another mother and another father with black button eyes and paper skin are waiting for Coraline to come to them. And they want her to stay with them forever. She knows that if she goes through that door, she might never come back.
