The Stone-Cursed King’s Blood Bride

Lena, a human girl, is offered as a sacrifice to Draven, a vampire king under a stone curse, and the two are bound together by a blood bond that ties their lives to one another. When the curse finally breaks, Lena spends seven years searching for the Blood Spring so she can bring Draven back from the brink. After she revives him, the pair take up the rule of the kingdom side by side, yet a strange red mark begins to glow from the depths of that same spring, hinting that an old witch's magic is not finished with them.
