As a eunuch in the Ottoman Imperial Harem, Olin has already lost his home, his freedom, and his manhood. Olin's only wish is for a painless death, until he meets Dark Star, a beautiful odalisque who promises to give him his deepest desire. He scoffs at her offer, not believing her claim to possess a jinni in a bottle. But when Dark Star is accused of witchcraft, Olin rubs the bottle in desperation and is astonished to find she's told the truth.
Olin becomes the jinni's master to save Dark Star, but it's not enough. In the complex world of the Topkapi Palace, where silk pillows conceal knives, sherbets contain poison, and jewels buy loyalty, no one is safe. As each wish brings unintended consequences, Olin must risk his life, his body, and his sanity to break the bonds that tie them all.
