Aradia Sicarius had always known what it was like to live with a constant threat of danger - after all, she lived in a world overrun by nasty hybrid creatures known only as the Others. But she hadn't known true fear until she lost both of her parents and accidentally sentenced both her brother and herself to imminent and brutal deaths. As if being exiled from her town with the Others so close to their borders wasn't bad enough, Aradia and her brother Finn find themselves caught up in a world beyond the crowded village they had always known - and they have no idea who they can trust.
