Shana, the legendary Frost, seals her magic to honor her mother’s promise and marries Julian, Lord of Lionheart City. For a year, she guards his city, manages his household, and cares for his mother as an ordinary wife. When Julian returns victorious, she catches him embracing the female mage Freya. He declares Freya his second wife and mocks Shana for her lack of magic. Heartbroken, Shana breaks her seal, reveals her true identity, annuls their marriage contract, reclaims her title as Duchess Grey, and takes back 500,000 gold coins before returning to Black Castle with her loyal followers. Julian and Freya try to crush her by cutting off supplies, but her former allies rally under the Grey banner. To command the Northern Army, Shana enters the Royal Legion officer trials. Despite their sabotage, she lifts 400-pound armor with one hand and shatters a high-level rune barrier with a single strike, stunning everyone. Meanwhile, Prince Benjamin, the young soldier she saved five years ago, watches quietly, waiting for the chance to protect the woman who once saved him.
