A sea of sky, a world of broken islands and shattered history, and flying ships ride the winds. Clarissa, a girl with no last name and no claim to anything beneath the endless blue, is sent to accompany a mysterious cargo aboard a ship of scoundrels. Flying beneath the lift bag of the Ravens' Child, accompanying the band of misfits and rogues that crew her, Clarissa begins to learn that the most profound mystery of her voyage is the one she takes with her.
