Till We Have Faces
In this fantasy novel loosely based on the myth of Cupid and Psyche, an unloved queen recounts her grievances against the gods, only to discover the struggle between selfish and unselfish love in her own soul. This is Lewis' most "feminist" book, showing a remarkable grasp of women's experiences in a male-dominated society.
