Five years ago, framed heiress Sylvia met Lucas, a 500-year-old Vampire King in bloodline frenzy. Pregnant and abandoned, she raised secret vampire twins in poverty. Now a bullied contractor designer, she whirlwind-marries a supposedly penniless, impotent construction worker—actually Voss Empire's billionaire ruler. Her cleaner matchmaker is the powerful Vampire Matriarch. When her abusive step-family endangers twins under deadly sun, their bloodline awakens. Lucas reveals himself for revenge.
