The battle for the Underworld has begun… When Hanna Heikkinen sacrificed herself to the God of Death to save her father, she never imagined she’d fall in love with the grumpy god—or thrive as Queen of Tuonela. Nor did she expect to uncover the truth of her divine lineage, a secret tied to powers far beyond her understanding. But when the Old Gods rise and Louhi’s dark forces plunge the Land of the Dead into Kaaos, threatening to destroy the balance of life and death, Hanna must fight for more than just her realm. With Tuonela unraveling and the souls of the dead at risk of eternal Oblivion, Hanna and Tuoni face impossible odds as love and duty collide. Can Hanna save Tuonela before it's lost to the void, or will her greatest sacrifice come at the cost of the one she loves most?
