Shadows Embrace — Kathryn Dona Lynn Jacks

Laura Irvine, the secret fiancée to Craig Bouyon, is the first to suspect that his death was not an accident. A year passes and a man by the name of Derrick Chavez shows up on her doorstep. Striking in appearance, but old fashioned in demeanor, he claims that he has something urgent to tell her, but Laura cannot overlook the sense of wrong that chases the man's words. He tells her things no one else should know - her blood type, the history of her family, and the fact that she was Craig Bouyon's fiancée. Laura discovers that there is a mutation in her blood that makes her the one individual susceptible to an empowering disease. In the darkest corners of Laura's mind, she knows that this man will bring her more agony and mystery than any other man in the world. Betrayed, alone, and forgotten, she steps into a vampire's shadow, wrenched into a torrent of living nightmares.
