Which 1950 C.S. Lewis novel begins with four siblings entering Narnia through a wardrobe?

The Lion, the Witch and the Wardrobe is the 1950 C.S. Lewis novel in which four siblings enter Narnia through a wardrobe. Peter, Susan, Edmund, and Lucy Pevensie discover the magical world while staying in an old country house during wartime.

Lucy is the first sibling to pass through the wardrobe. She encounters Mr. Tumnus, a faun, and learns that Narnia is under the rule of the White Witch. The other children eventually follow her, and their arrival becomes part of a larger struggle involving Aslan and the restoration of Narnian freedom.

The book was the first Narnia novel Lewis published, although many modern editions arrange the series in the fictional chronological order beginning with The Magician’s Nephew. That difference sometimes causes confusion about which book “comes first.”

Prince Caspian, The Voyage of the Dawn Treader, and The Silver Chair are later Narnia books. None introduces the wardrobe as the gateway into the series’ central adventure.
