Catherine Hunter is one of the lucky ones. Fourteen years old, a daughter of privilege, she doesn't need to fear the Collections which rip other Anglyan families apart. But she longs for escape - before her dad can marry her off to a rich government brat and imprison her forever. So Catherine becomes Cat, and stows away on the skyship Stormdancer. But the ship's small, courageous crew have secrets of their own. As they brave the storms that fill the skies between islands, Cat must choose: loyalty or freedom; family or truth; love or battle? Let the skies decide.
