Malin's mission to avenge her mother's murder has uncovered dangerous secrets. As a Valkyrie-in-training, Malin must slay immortals who've had their time, to maintain balance between humans and immortals. But her quest could destroy earth's stability - and unleash chaos.
Just when she needs to focus, her friend Asher is in grave danger. He's been dragged into the underworld, where vengeful immortals plot revolution. Malin believes her feelings mustn't distract from her goal - but is desperate to rescue him. So she ventures into the darkest of realms, knowing she may not survive. With new allies at her side and new enemies ahead, Malin will face terrible choices. She'll have to keep her head - or be ruled by her heart.
