Heartstone Oaths, the Frozen Court, and the War to Come

In a world where oaths are bound by magic and broken at peril of death, a reluctant heir must navigate the treacherous politics of an eternal winter court to prevent a war that could shatter continents. Elara, bearer of a legendary Heartstone, never wanted the throne-only to protect her people. But when an ancient enemy stirs beyond the glacial walls, she is thrust into a deadly game of intrigue within the Frozen Court, where every smile hides a dagger and every alliance demands a price in blood.
To survive, she must forge uneasy bonds with exiled warriors, cunning spymasters, and a rival prince whose frosty exterior may melt for a cause greater than his own ambition. As the ice begins to crack and armies gather, Elara must decide what she is willing to sacrifice: her oath, her heart, or her world.
