Chronicles of Narnia book #6 Collector's Edition
NARNIA . . . where owls are wise, where some of the giants like to snack on humans (and, if carefully cooked, on Marsh-wiggles, too), where a prince is put under an evil spell . . . and where the adventure begins.
Eustace and Jill escape from the bullies at school through a strange door in the wall, which, for once, is unlocked. It leads to the open moor . . . or does it?
