Which C.S. Lewis book uses the fictional author Orual to retell Cupid and Psyche?

Till We Have Faces uses the fictional author Orual to retell Cupid and Psyche.

Published in 1956, Till We Have Faces: A Myth Retold is Lewis’s final work of fiction. Its narrator, Orual, is a queen who looks back on her life and her relationship with her half-sister Psyche. The novel reworks the classical myth of Cupid and Psyche from Orual’s point of view.

Lewis described the book as a retelling of a story that had interested him for many years. Unlike the Narnia books, it is aimed at adult readers and uses a darker psychological and philosophical style.

The title comes from the novel’s concern with identity, self-knowledge, and the inability to perceive divine reality clearly. It is sometimes confused with Lewis’s final published novel, The Last Battle, but Till We Have Faces is a separate mythic work.
