The Silver Chair

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? Once again Aslan has a task for the children, and Narnia needs them. Through dangers untold and caverns deep and dark, they pursue the quest that brings them face to face with the evil Witch. She must be defeated if Prince Rilian is to be saved.
King Caspian's beloved son Prince Rilian has disappeared. Aslan sends Eustace and his school friend Jill to Narnia on a quest to search for the young prince and defeat the evil Witch.
Two English children undergo hair-raising adventures as they go on a search and rescue mission for the missing Prince Rilian, who is held captive in the underground kingdom of the Emerald Witch.
