C. S Lewis

Four English schoolchildren find their way through the back of a wardrobe into the magic land of Narnia and assist Aslan, the golden lion, to triumph over the White Witch, who has cursed the land with eternal winter.

Aboard the "Dawn Treader," the royal vessel of King Caspian, Edmund, Lucy, Eustace, and the crew of the vessel search for the seven lost lords of Narnia.
