Which Narnia book features the Pevensie children entering a snowy world through a wardrobe?

The Pevensie children enter Narnia through a wardrobe in The Lion, the Witch and the Wardrobe.

C.S. Lewis published this book in 1950 as the first released volume of The Chronicles of Narnia. The central children are Peter, Susan, Edmund, and Lucy Pevensie. Lucy discovers the wardrobe during a game of hide-and-seek and finds a snowy forest on the other side.

The story’s Narnian conflict involves the White Witch, whose rule has brought a perpetual winter, and Aslan, the great lion. The book combines portal fantasy, talking animals, battles, prophecy, and themes drawn from Christian symbolism.

A common source of confusion is the series chronology. The Lion, the Witch and the Wardrobe was published first, but The Magician’s Nephew later provided an origin story for Narnia and is often placed first in chronological reading order.
