What was C.S. Lewis’s only published novel for adults that retells the Cupid and Psyche myth?

Till We Have Faces was C.S. Lewis’s adult novel retelling the Cupid and Psyche myth.

Published in 1956, Till We Have Faces: A Myth Retold is Lewis’s final work of fiction and his last completed novel. It retells the ancient myth of Cupid and Psyche from the perspective of Psyche’s older sister, Orual, who becomes queen of the fictional kingdom of Glome. The novel explores love, jealousy, identity, self-knowledge, and the difficulty of seeing the truth clearly.

Lewis regarded the book as one of his best works, yet it initially received less popular attention than his Narnia stories and Christian apologetics. Its title refers to the idea that people must confront reality honestly rather than hide behind accusations or self-protective identities. The book is often described as Lewis’s only adult novel, distinguishing it from his children’s fiction and from works such as The Great Divorce, which is a theological fantasy or allegorical tale rather than a conventional realist novel.
