Dying Of The Light by George R. R. Martin

Set on the dying planet of Worlorn, a world once vibrant with life during a festival of cultures but now fading into darkness, the story follows Dirk t'Larien as he responds to a cryptic call from his former lover, Gwen Delvano. As Dirk navigates the haunting remnants of the festival and the complex web of relationships, he becomes entangled in a conflict involving Gwen's new partner, Jaan Vikary, and the rigid traditions of the Kavalar people. Themes of love, loyalty, and the struggle against inevitable change are explored as the characters confront their pasts and the looming end of Worlorn itself.
