A thousand-year-old vow, etched by ancestors long forgotten—now it falls to her. Seventeen-year-old swordswoman Sara inherits a forbidden two-sword style passed down through blood. With a lone wolf pup at her heels, she leaves her village behind and steps into war’s shadow, hunting the myth of the Five Heavenly Swords. Through blood, betrayal, and endless nights, she uncovers what destiny truly demands. Across the same fractured continent, merchant Denaro discovers Ronaal Steel—a blade-forging legend worth empires. What starts as trade ambition spirals into espionage: secret alliances, border crossings, and sabotage against rival kingdoms. One wrong move, and he becomes the spark that ignites total war. Two lives—one blade, one coin—caught in history’s unforgiving current. A dual-POV military-historical fantasy.
