In a world where infants with magical powers are torn from their parents to be raised exclusively by the mysterious and powerful Danisoba, Kestrel has managed to keep her abilities concealed–and herself free. She hid when they killed her parents, lived as a street urchin in back alleys, and then served as a young tavern maid before escaping to sea, where magic is canceled by water. Now an adult and quartermaster of a pirate ship, Kestrel loves the freedom of living on the seas. But her way of life could end if anyone on board learns her closely guarded secret–that she has magical control over the wind.
One day a black ship appears, and her life changes. Its captain is a handsome rogue of whom Kestrel is strangely, constantly aware. When Kestrel’s captain is led into a trap and is arrested, Kestrel gathers her crew and sets sail in relentless pursuit.
