"Coraline discovered the door a little while after they moved into the house. . . ."
When Coraline steps through a door to find another house strangely similar to her own (only better), things seem marvelous.
But there's another mother there, 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 courage if she is to save herself and return to her ordinary life.
I really feel as though I would have liked having Coraline for a best friend - she's quite a clever child, and very witty and brave. Even though the other mother was scary as hell, Coraline still managed to stand against her, no problem. This was yet another instance in which the book far outshines the movie, if only because I feel that this story is best experienced through Gaiman's writing. Though, for other aficionados of the film, I must say that the biggest difference (to me) between the movie and the book was that Wybie was not in the book - he was a character specifically created for the movie. The book didn't really need him, either, as it fits Coraline's personality to be more independent.
A highly recommended book - especially around Halloween!
