After the recent success of his new book Max is on a roll. He finally has the home and family denied him as a child. His wife, Renee, is a raven-haired stunner and brilliant systems analyst but the love of his life is a beautiful, unusually gifted, seven-year old daughter named Lizzy. All is right with world until an ancient evil cast its shadow over Max Carter's life. A vampire slaughters Renee and takes Lizzy hostage in a cruel game of kill me if you can. Challenged to Shibboleth, Max must find and destroy the vampire to save his daughters' life and his own immortal soul. Time is running out for Max. He must not only elude the police, who have implicated him in his wife's murder, but struggle with his own transformation into a vampire. Max is aided by his assistant, Kim, and Dr. Nicoli Themas, an ancient and mysterious academic. As he struggles to save Lizzy and his own humanity, little does he realize there are much darker forces at play? A malevolent force of nature has awakened, a bastard incarnation of a Nephilim and an immortal. A power so dark and powerful that God himself denied it physical form fearing it might breach the threshold between the darkness and the light and destroy mankind. A hybrid of the serpent seed, plagued by an immortal hunger and a deep abiding hatred of mankind, it stalks the darkness, restlessly waiting until its time is come.
