Which C.S. Lewis novel is set partly in the fictional ancient kingdom of Glome?

Till We Have Faces is the C.S. Lewis novel set partly in the fictional ancient kingdom of Glome.

Published in 1956, the novel retells the myth of Cupid and Psyche from the perspective of Orual, a princess and later queen of Glome. The story examines love, jealousy, religious belief, self-knowledge, and the difficulty of seeing other people clearly. Its title comes from the idea that a person must confront an honest, recognizable self before truth can be understood.

Lewis described the book as a retelling of the Cupid and Psyche story, but it is not a simple classical adaptation. The narrator’s viewpoint, the invented kingdom, and the psychological depth distinguish it from his Narnia books. Till We Have Faces was Lewis’s final published novel and is often regarded as one of his most sophisticated works of fiction.
