Leif Skarsganger and his elite band of immortal warriors have been charged to protect humanity from the evil Norse god Loki. Under attack from Loki's minions, Leif is shocked to encounter a dark-haired beauty who fights like a warrior herself. Wounded and feverish, the Viking kisses her, inadvertently triggering an ancient Norse bond. But when Naya Brisbane breaks away and disappears before the bond is completed, Leif's warrior spirit goes berserk. If Leif doesn't find her fast, he's going to lose himself to permanent battle fury. But Naya doesn't want to be found...and he'll do anything to find her. Because they're both running out of time.
