She also struggles to maintain balance in her own life - between her studies, her duties as a Valkyrie and her conflicting feelings for her ex-girlfriend. But when a beguiling stranger breaks into her home on a quest for vengeance, Malin's carefully balanced life falls apart. Asher is hunting the rogue immortal who murdered his mother, and he thinks Malin may have information. Her loyalties are tested, as she uncovers a betrayal that unravels everything she thought she knew.
