The Last Battle by C.S. Lewis is the final novel in the Narnia series. The story is set some 2500 Narnian years since the creation of the world as told in The Magician's Nephew. A false Aslan is set up in the borderlands, and conflict ensues between true and false Narnians and between Narnia and Calormen, whose people worship the malevolent Tash. With its dark imagery and sinister tone, The Last Battle seems to be more of an adult than a children’s book. The story concludes with the termination of the world by Aslan and the entry of believers into eternal life in the final kingdom. The Last Battle won the 1956 Carnegie Medal from the Library Association.
