The Lion, the Witch and the Wardrobe is the most famous of the Narnia Chronicles by C.S. Lewis, which are a set of stories set in a fictional land watched over by a lion called Aslan. The second in the series, the story of the book revolves around four siblings who escape from wartime London to an old country house, and find a gateway to Narnia at the back of a wardrobe. Once there, they are called upon to save the land from the White Witch, who has cast a spell so that it is always winter, but never Christmas- a terrible prospect!
The film version of the book, brought out in 2005, inspired several artists to write songs for it. These have since been made into an album, which is great listening if you want to relive this childhood classic.
