When Coraline steps through a door in her family's new house, she finds another house strangely similar to her own (only better). At first, things seem marvelous. The food is better than at home, and the toy box is filled with fluttering wind-up angels and dinosaur skulls that crawl and rattle their teeth. But there's another mother and another father, and they want her to stay and be their little girl. They want to change her and never let her go. Coraline will have to fight with all her wit and all the tools she can find if she is to save herself and return to her ordinary life.
Looking for excitement, Coraline ventures through a mysterious door into a world that is similar, yet disturbingly different from her own, where she must challenge a gruesome entity in order to save herself, her parents, and the souls of three others.
