The Last Battle

The Last Battle is a high fantasy novel for children by C. S. Lewis. It was the seventh and final novel in The Chronicles of Narnia (1950–1956).
The Last Battle is set almost entirely in the Narnia world and the English children who participate arrive only in the middle of the narrative. The novel is set some 200 Narnian years after The Silver Chair and about 2500 years (and 49 Earth years) since the creation of the world narrated in The Magician's Nephew. A false Aslan is set up in the north-western borderlands and conflict between true and false Narnians merges with that between Narnia and Calormen, whose people worship Tash. It concludes with termination of the world by Aslan, after a "last battle" that is practically lost.
