On a continent ruled by three empires, some are born with a 'witchery,' a magical skill that sets them apart from others. Safiya is a Truthwitch, able to discern truth from lie. Iseult is a Threadwitch, seeing the invisible ties that bind and entangle the lives around her-- but not those that touch her own heart. With the help of Prince Merik, a Windwitch-- and the hindrance of a Bloodwitch bent on revenge-- the friends must fight emperors, princes, and mercenaries alike, who will stop at nothing to get their hands on a Truthwitch.
