After rescuing a stranger in need, Isolde falls for him, never imagining he would vanish and leave her pregnant. Her secret grows into two golden leopard cubs with royal blood, hidden from the world. Now the King at Blackthorn Keep summons her back as his Queen—yet he is the very man she lost. Carrying the cubs into the palace, Isolde faces the one risk she cannot control: the soft cries of her babies may reveal everything.
