The faerie Magpie Windwitch, granddaughter of the West Wind, flies over the ocean with her small flock of crows. Ill-advised sailors all too often open bottles floating near their ships, and Magpie has vowed to recapture the devils released upon the world from their sea-borne containers. But there is one bottle in which a great menace was trapped by the ancient Djinn King, and when this bottle is opened, the evil of the Blackbringer threatens to engulf the world. Magpie has never faced anything even remotely as dangerous, and her quest to save the land soon involves dragons, a tattooed princeling, and Magpie's hero, the legendary Bellatrix.
