In the war-torn kingdom of Valedorne, Princess Y/N of House Auremont is promised to a foreign prince to secure peace between rival nations. Proud, politically sharp, and raised to distrust warriors, Y/N despises the brutal knight assigned as her royal protector: Sir Kael Draven, a disgraced battlefield legend rumored to have slaughtered hundreds during the Border Rebellions. Kael, meanwhile, views the princess as another sheltered royal who knows nothing of sacrifice or survival. When an assassination attempt forces them to flee the capital together, the two enemies are dragged across cursed forests, ruined cathedrals, and enemy territory while hunted by traitors from both kingdoms. As secrets unfold, Y/N discovers Kael’s terrifying reputation hides a man broken by guilt rather than driven by cruelty. Kael slowly realizes the “cold princess” is trapped in a political cage she never chose. But their growing feelings threaten not only their lives — but the fragile peace between kingdoms. To love each other would mean betraying everything they were born to protect.
