The Chronicles of Narnia is a series of seven books: "The Magician's Nephew,; "The Lion, the Witch, and the Wardrobe," "The Horse and His Boy," "Prince Caspian," "The Voyage of the Dawn Treader," "The Silver Chair" and "The Last Battle." The stories center on the magical land Narnia, which is filled with mythological creatures and talking animals. The great lion, Aslan, is a Christ-figure in the series, appearing in each book. He watches over Narnia and intervenes throughout its history.
"The Magician's Nephew" explains how Aslan first created Narnia. Digory, a young boy, and his neighbor, Polly, use magic rings to travel between different worlds. They witness Aslan creating Narnia, and are responsible for enabling the evil White Witch to enter its borders. Digory and Polly bury their magic rings with an apple core from a Narnian tree; a new apple tree grows from its seeds, and Digory uses its wood to build the wardrobe that the Pevensies use to enter Narnia.
"The Lion, the Witch, and the Wardrobe" tells how Lucy, Edmund, Susan and Peter Pevensie discover Narnia by walking through a magic wardrobe. The children join Aslan's army and fight the White Witch. The Witch attempts to defeat Aslan by demanding Edmund's life. Aslan offers his life to the Witch instead; however, after she kills him, he rises from the dead and defeats her with his army of talking beasts. In the end, he crowns the children kings and queens of Narnia.
In "The Horse and His Boy," a boy named Shasta escapes from the land of Calormene with a Narnian horse called Bree. Together with a girl named Aravis and a mare named Hwin, they save Archenland from a Calormene invasion. Ultimately, Shasta learns that he is actually the lost prince Cor of Archenland.
