Schiava per Amore, Regina per Sangue

Half-blood vampire Aurora saves pureblood Julian—but her sister steals the credit. Used and drained for three years, she breaks the Blood Bond and escapes, barely alive. The First Blood King finds her, awakens her royal bloodline and past-life memories. When Julian learns the truth, he crawls back to beg—but she's already rising to the throne beside the true king.
