Rebel Skies by Ann Sei Lin is a fantasy novel set in a world of floating cities and flying ships. Kurara is a servant on one of those ships, the Midori when she discovers that what she thought was her secret talent - making paper figures come to life just using her fingers--is actually a prized and somewhat feared skill in the Mikoshima empire. When the Midori is attacked and her secret discovered, Kurara embarks on a new life and mission joining a new skyship to hunt the shikigami, wild paper spirits that are coveted by the Imperial Princess for reasons that remain mysterious. But, as Kurara embraces her new life, she’s troubled by the ethics of hunting paper spirits that might have souls and minds of their own and begins to wonder if she herself might be in danger.
