The battle of good against evil is fought in the magical world of Narnia, in the most enchanting fantasy novels ever written. Lucy and Edmund, with their odious cousin Eustace, journey on board the gallant ship, the Dawn Treader, to the Eastern Islands in search of the seven lost friends of King Caspians father. On this extraordinary voyage of discovery they encounter a dragon, a sea serpent, a band of invisible people, a magician, and also the great Aslan himself, who makes them a very special promise.
