In Geneva, Maria drifts further and further away from love as she develops a fascination with sex. Eventually, Maria's despairing view of love is put to the test when she meets a handsome young painter. In this odyssey of self-discovery, Maria has to choose between pursuing a path of darkness, sexual pleasure for its own sake, or risking everything to find her own "inner light" and the possibility of sacred sex, sex in the context of love.

In this gripping and daring new novel, Paulo Coelho sensitively explores the sacred nature of sex and love and invites us to confront our own prejudices and demons and embrace our own "inner light."
