What was the title of C.S. Lewis’s first book about Narnia’s creation, published in 1955?

The Magician’s Nephew was C.S. Lewis’s book about Narnia’s creation, published in 1955.

It follows Digory Kirke and Polly Plummer as they travel between worlds using magical rings made with the help of Digory’s uncle, Andrew. Their journey leads to the creation of Narnia, where they witness Aslan singing the new world into existence. The story also explains the origin of the wardrobe’s magical wood.

Although The Magician’s Nephew is first in Narnia’s internal chronology, it was the sixth book published. The Lion, the Witch and the Wardrobe came first in 1950, and that publication order shaped the experience of the original readership. Digory later appears as the professor who owns the house containing the wardrobe, linking the series’ beginning to its first published adventure.
