Orphaned monster hunter Ella infiltrated an ancient gothic citadel to rescue her missing boyfriend, only to accidentally awaken Kane, a primordial vampire monarch who slept for ten centuries. Kane forces her into an intimate blood thrall covenant, only for Ella to uncover the devastating reality that her boyfriend deliberately used her as expendable sacrificial bait.
When the corrupt Guild Master who murdered Ella's parents arrives to purge the crypt, Kane sacrifices his own immortal heart to shield her from the onslaught. Igniting Ella's dormant primordial lineage, she ascends as the supreme half-vampire queen, restoring Kane's shattered core and executing the traitors who manipulated her entire life.
