Conflict flares once more in Saxony. March, AD 773. Bjarki Bloodhand is now Fire Born - a legendary berserker inhabited by the ferocious spirit of a bear in battle. Yet he has sworn never again to allow that sacred rage to possess him, lest he for ever lose himself in the madness like his father. Tor Hildarsdottir yearns to save pagan Saxony from the grip of the Christian Franks, who now occupy half the region. But she also has serious problems closer to home with her fast-growing pet bear cub, Garm, and, worse, she seems to be falling in love. Widukind, new lord of the Saxons, is on a mission to reconquer the lands of his fathers from the Franks. He will stop at nothing to win the hearts of the men and women of the North, and bind them to his cause. But will they follow the Saxon Wolf in an unwinnable war? And will Bjarki join them?
