Daughter of an ousted king, descendant of ancient druids, as a child it is prophesied that one day Gruoch will be queen of Alba. When she is betrothed to Duncan, heir elect, this appears to confirm the prophecy. She leaves behind her home, her family and her close friend MacBethad, and travels to the royal seat at Scone to embrace her new position. But nothing is as Gruoch anticipates. A suspenseful, sweeping historical epic, and the story of the woman who inspired one of Shakespeare's most iconic characters.
