What is the title of C.S. Lewis’s seven-book fantasy series set partly in Narnia?

C.S. Lewis’s seven-book fantasy series set partly in Narnia is The Chronicles of Narnia.

The series begins with The Lion, the Witch and the Wardrobe, published in 1950, and concludes with The Last Battle, published in 1956. Across the books, children from England enter the world of Narnia, where they encounter talking animals, magic, wars, and the great lion Aslan.

The internal chronology differs from the original publication order. The Magician’s Nephew takes place earliest in Narnian history, while The Last Battle brings the series to its conclusion. Many editions number The Magician’s Nephew first, but Lewis originally published The Lion, the Witch and the Wardrobe first.

The books combine fairy-tale motifs with Christian symbolism, classical mythology, and Lewis’s interest in medieval literature. They have been translated widely and adapted for radio, television, stage, and film. The seven titles are often sold together as a single collected set, although each volume is a complete novel.
