On a lonely Scottish island stands a stone tower which harbors a terrible secret deep within... Half-blood witch Dara Martin has been given a second chance to redeem herself in the eyes of the ruling Witch Kin. They'll teach her how to wield her powerful natural magic and eventually, maybe, to work with Hugh, as long as she gives up her errant ways. But the tower's mystery inevitably draws her in, and while she has sworn not to lie to the Kin, she must hold on to her own secrets or lose her only chance of freeing her mother...
