Probably the most famous of the Narnia books, The Lion the Witch and the Wardrobe tells how four siblings - Lucy, Peter, Susan and Edmund - find a magic wardrobe that takes them to a world of talking animals. With the help of the lion Aslan they must defeat the White Witch who has made it always winter and never Christmas. But sibling rivalry makes the task tricky, and the four children must unite themselves before they can defeat the enemy.
