'The Last Battle' by CS Lewis concludes the Narnia series of novels. The story takes place 2500 Narnian years since the creation of the world as related in 'The Magician's Nephew'. The ape Shift sets up a false Aslan, starts to order his fellow Narnians around and causes conflict between true and false Narnians, and between Narnia and Calormen, whose people worship the malevolent Tash. With its dark imagery and sinister undertone, 'The Last Battle' seems to be more of an adult's book 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.
