Iceland, AD 935.
Einar Unnsson is destined to be great. When he fights, a frenzy comes upon him. It makes him lethal in battle so lethal he just defeated the man his own father sent to kill him.
Now, with Einar exiled from his kingdom, his father turns his vengeance on Einar’s mother, his escaped former bedslave. Yet Einar is in no position to protect her. He’s made an enemy of the powerful King Eirik and must fight for his own life before he can save her.
Einar depends on the Wolf Coats, a band of fearsome, bloodthirsty warriors, but they’re convinced the fates have cursed them. Will Einar’s skill in battle be enough to save his mother? Or will the Wolf Coats’ superstition destroy them all?
