Prince Caspian calls on Lucy, Edmund, Peter, and Susan back to Narnia in his most harrowing time of need. Led by Aslan, the Great Lion, the children help young Caspian defeat corrupt King Miraz in a spectacular battle, restoring Narnia to its full glory. Years later, Lucy and Edmund are sent back to Narnia, along with their cousin Eustace, to assist Caspian on a voyage. Along their journey the children battle dragons and sea serpents, and sail across a golden lake to reach the edge of the world.
