Which C.S. Lewis novel was published in 1956 and won the Carnegie Medal?

The Last Battle was published in 1956 and won the Carnegie Medal.

The Last Battle is the seventh and final published novel in C.S. Lewis’s The Chronicles of Narnia. It tells of the final conflict in Narnia, involving the ape Shift, the donkey Puzzle, and a false representation of Aslan. King Tirian is the last Narnian monarch shown in the main action.

The book appeared in 1956 and received the Carnegie Medal in 1957. The Carnegie Medal is awarded annually by the Chartered Institute of Library and Information Professionals for an outstanding English-language children’s book published in the United Kingdom.

Readers sometimes confuse publication order with the internal chronology of the Narnia world. The Last Battle is the conclusion in both the publication sequence and the broad narrative arc, while The Magician’s Nephew explains Narnia’s origin but was published later than the first five books.
