In a world of flight, he was born wingless. But that's the least of his problems. Since being orphaned at a young age, wingless sprite Asher Songfeather has been sure of one thing: Bat sprites aren't to be trusted. The fact that his own mother was one is something Asher does his best to forget. But when his adoptive sister Carinen falls deathly ill, he'll risk anything to save her-even if it means striking a bargain with a mysterious Bat sprite newcomer. The deal sends Asher on a perilous quest into the heart of the Bat Colony itself, where nothing is as it first appears. Saving his sister will require more than just courage and wits. It will take trust, too. And Asher will have to rethink everything he knows about Bat sprites-including himself.
