Chronicles of Narnia: The Silver Chair !!!

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. Illustrations.
