The story follows Caspian X, the rightful Telmarine heir, who flees his usurping uncle Miraz and joins forces with the Old Narnians (dwarfs, centaurs, and the delightfully truculent Trumpkin) to reclaim his throne. With the Pevensies’ help—and the long-awaited return of Aslan—Caspian must awaken Narnia’s dormant magic and restore its rightful order.
Lewis weaves medieval adventure with Christian allegory (Aslan’s sacrificial path mirrors Christ’s), while themes of faith, leadership, and the erosion of tradition resonate throughout. The novel’s climax—a David-and-Goliath battle at Aslan’s How—cements its place as a classic of children’s literature.
