Calla Voronín thought she knew her destiny. Marry her village's next leader and become the sacred Seer, a human blessed with the gift of precognition. And yet, when the infamous shifters of the North invade her homeland on the day of her wedding in search of gold, food, and women, Calla realizes she does not have as much control over her destiny as she thought.

Like the icy and unforgiving nature of the northern continent, Alpha Einarr Fjerstäd treats those that he conquers with little mercy. Under the flag of the Alpha King, he holds no qualms about invading human villages and leaving nothing but ash and bone in his wake. But when his pack's longship lands on the shores of Calla Voronín's seaside city, the infamous Alpha stumbles upon a treasure far greater than any loot.

Stolen away to her supernatural captor's frigid homeland, Calla is determined to do everything in her power to punish Alpha Einarr and return to her family. And yet, with every second spent amongst the legendary shifters and beside the man who claims to be her mate, Calla's resolve to escape weakens. In a struggle against her own desire, Calla must decide whether to forsake her werewolf captors or step into her role as Luna-- ruler of the Alpha's heart.
