The Last Battle is C.S. Lewis’s final completed novel in The Chronicles of Narnia.

Published in 1956, the book concludes the seven-volume Narnia series. Its plot centers on a false Aslan, political and religious deception, and the final conflict that brings Narnia’s history to an end. The story then presents a renewed country that the characters recognize as more real than the old Narnia.

The Last Battle won the Carnegie Medal in 1957, an important British children’s literature prize. Publication order and internal chronology differ across the series, but The Last Battle is the seventh and final book in both the release sequence and the traditional numbered set. The title signals its role as the series’ concluding volume.
