Which Narnia book concludes C.S. Lewis’s seven-volume series?

The Last Battle concludes C.S. Lewis’s seven-volume The Chronicles of Narnia.

Published in 1956, the novel brings the series’ long-running conflict to its final stage. King Tirian faces deception, political collapse, and the destruction of the old Narnia. The story also revisits major characters and ideas from earlier books, giving the series a deliberately concluding shape.

The title refers to the final conflict within Narnia, not to the first major battle readers encounter. The Lion, the Witch and the Wardrobe, published in 1950, begins the publication sequence, while The Last Battle closes it six years later.

The Silver Chair and The Voyage of the Dawn Treader are earlier installments, and The Horse and His Boy is also set before the finale. All seven books together form Lewis’s Narnia cycle, with The Last Battle as its concluding volume.
