I traded my light to the monster of the dark. But the true villains are the ones who built the sun. Liora is a "Moth"—a rare human born with a dangerous, caged light magic in a world slowly freezing to death. For years, she has hidden her power, watching her village starve under the oppressive rule of the so-called holy Radiant Vanguard. But when the Vanguard burns her people’s last winter harvest, Liora makes a desperate, suicidal choice. She crosses the treacherous Dead Barrens into the cursed domain of Nocturne to strike a bargain with the continent's most feared warlord. Her magic, in exchange for her people's survival. Mordane is the Shadow King. For three centuries, the agonizing "Void-Blight" has eaten at his mind, turning him into a ruthless, immortal weapon. He needs Liora's pure light to hold back the madness. She needs his dark army to stay alive. It was supposed to be a simple, cold transaction. But trapped within the freezing, iron-wrought walls of his fortress, the ice between the monster and his captive begins to melt. Beneath the terrifying armor, Liora discovers a fiercely protective king who would burn the world to ashes just to keep her safe. But the shadows of Nocturne are not their true enemy. The Radiant Vanguard are not saviors; they are parasites, siphoning the continent's magic to fuel their artificial sun and their own twisted immortality. To save their dying world, a fractured light-weaver and a cursed king must do the impossible: march into the heart of the Vanguard's shining paradise and tear it down from the inside. If they fail, the world freezes in eternal darkness. If they succeed, Mordane will lose his immortality forever—and Liora might lose the only man who truly sees her.
