Betrayed by her stepsister and cast into Saint Night Academy, human Eloise is near death until she awakens Darius—the mad original vampire king, sealed for a century—who brands her with his Thorned Origin Seal. Her dormant saint blood surges awake, while werewolf alpha Lucas claims her as his fated mate, sparking a bloody tug-of-war. On the blood moon, the High Council sentences Eloise to burn; Darius takes a fatal blow for her, but she sacrifices her holy blood to unleash his full power. Together they slaughter the elders, storm the grand cathedral, kill Grand Elder Vladimir, and drown the ancient order in blood. Her saint blood merges with pure vampire lineage, granting her immortality and gilded wings. Crowned dual monarchs of all dark races, they rule from two bone thrones—bound by a twisted, all-consuming love that ends the old laws and begins their eternal reign.
