For twenty years, Ilian has lived as Lothern's only prince. But beneath the disguise lies a secret that could cost her life—she's actually a princess. When her sister Cecilia is sold to the beastmen, Ilian gives up her royal title and becomes a slave to save her. But inside the brutal Gloom Empire, something awakens in her blood. Her hidden Variant nature draws the attention of Alistair, a savage Beast King who lost his mind a century ago. To everyone's shock, Ilian is his fated mate—the only one who can bring him back. But can a human princess tame a beast feared by an entire empire? Or will their forbidden bond destroy them both?
