Which novel did C.S. Lewis publish in 1956 about an ancient kingdom and a woman named Orual?

Till We Have Faces is the C.S. Lewis novel published in 1956 about Orual and an ancient kingdom.

The book is Lewis's retelling of the myth of Cupid and Psyche, presented largely through the voice of Orual, queen of the fictional kingdom of Glome. Orual struggles with love, jealousy, grief and the difficulty of seeing the gods and other people clearly. The title comes from the book's central concern with hidden motives and the need for honest self-knowledge.

Lewis regarded Till We Have Faces as one of his best works. It differs from the Narnia books in audience, tone and setting, using a psychologically complex first-person narrative rather than a children's fantasy adventure.

The novel appeared late in Lewis's career, after his major works of Christian apologetics and most of the Narnia books had already been published. Its classical source is sometimes mistaken for a direct retelling, but Lewis substantially reshaped the myth through Orual's perspective.
