Which C.S. Lewis novel tells the story of Orual and Cupid?

Till We Have Faces tells the story of Orual and Cupid in a retelling of the Cupid and Psyche myth.

Published in 1956, the novel is narrated by Orual, a princess and later queen of the fictional kingdom of Glome. Her account centers on her relationship with her half-sister Psyche and on her anger toward the mysterious god whom she believes has taken Psyche away.

The book’s full title is Till We Have Faces: A Myth Retold. Lewis developed it with help from his knowledge of classical mythology and from conversations with Joy Davidman, who later became his wife. Unlike the Narnia books, the novel is aimed at an adult readership and uses a psychologically complex first-person narrator. Its themes include love, possessiveness, self-knowledge, and the difficulty of recognizing one’s own motives.
