"I think I'll have to go right back to the beginning and tell you how Caspian grew up in his uncle's court and how he comes to be on our side at all. But it'll be a long story." "All the better," said Lucy. "We love stories." And so the Dwarf Trumpkin tells the children of how young Caspian escaped his uncle Miraz, false King of Narnia, and found his true calling leading the Old Narnians in the fight for their freedom.
Peter, Susan, Edmund, and Lucy are suddenly pulled into Narnia from their own land of England by a distress call from Prince Caspian. It has been hundreds of years since the time described in The Lion, the Witch, and the Wardrobe, when the children reigned over the land as benevolent Kings and Queens. Now most of the Talking Beasts and enchanted creatures who once lived there in peace have been killed or frightened into hiding. Only Caspian and the rulers of Old Narnia, with the help of the great Aslan, can liberate Narnia and make it safe for its rightful inhabitants.
Prince Caspian was the second book written by C.S. Lewis in the Chronicles of Narnia series, but it is considered to be the fourth in the series by those wishing to read the books in chronological rather than publishing order.
