In a world where infants with magical powers are torn from their parents to be raised by the mysterious and powerful Danisoba, who have a monopoly on magic, Kestrel has managed to keep her abilities concealed - and herself free. First hiding in back alleys as a street urchin, she hid when they killed her parents, and then served as a young tavern maid before escaping to sea, where magic is cancelled by water.
Now an adult, as the 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, she gathers her crew and sets sail in relentless pursuit...
