In the harsh Scottish highlands of 1565, superstition and treachery threaten a truce between rival clans. It's a weak truce at first, bound only by an arranged engagement between Anne MacGregor and Niall Campbell - the heirs of the feuding families.
While Niall wrestles with his suspicions about a traitor in his clan, Anne's actions do not go unnoticed. And as accusations of witchcraft abound, the strong and sometimes callous Campbell heir must fight for Anne's safety among disconcerted clan members. Meanwhile his own safety in threatened with the ever-present threat of someone who wants him dead.
Will Niall discover the traitor's identity in time? Can Anne find a way to fit into her new surroundings? Will the two learn to love each other despite the conflict?
