Bloodline of the Crimson King

Lucian, supreme Blood King of the vampire clan, finds a tortured girl bearing his royal golden blood mark on his border. He realizes she is his long-lost daughter Seraphina, while the empress in the human palace is a fake. Traitor Lilith and a robed sorcerer used dark magic to steal Seraphina’s identity, murdered the real human king, and plan to sacrifice Seraphina’s infant to break an ancient seal and unleash a world-destroying demon. Lucian gathers all blood kin warriors to march on the human capital and stop the fatal full-moon ritual to save his family and the whole world.
