Which C.S. Lewis novel begins with Lucy discovering a passage through a wardrobe?

The Lion, the Witch and the Wardrobe begins with Lucy discovering a passage through a wardrobe.

Lucy Pevensie enters the wardrobe while playing hide-and-seek at an old country house. Instead of finding the back of the furniture, she emerges into a snowy wood in Narnia and meets Mr. Tumnus. Her siblings later follow her into the same world.

The novel introduces the Pevensie children, Aslan, the White Witch, and the central conflict over Narnia’s long winter. Lewis published it in 1950, making it the first Narnia book released to readers, even though it is second in the series’ internal chronology.

A common mix-up concerns the title’s punctuation and order: “the Witch” and “the Wardrobe” are both part of the canonical title. The story was adapted into a major feature film in 2005.
