Jack Pike is an ordinary family man who gets caught up in the plans of a vampire. From the very beginning Jack has a growing sense that an evil being is interested in his unborn son. More and more, Jack and his family have to take steps to deal with the growing abomination which preys upon them. As his wife progresses into her pregnancy, she and the other women, of a variety of ages and roles, come to realize a dreaded male presence is growing stronger and more focused. Jack researches the records of similar histories of this type whose outcome was the death of the mother carrying the unborn males. Friends and loved ones band together to shield the mother from harm. Soon those who are close to the Pikes realize that the source of evil is the dreaded and ancient Tirgov. This timeless vampire demonstrates a sordid history of turning male infants into his apprentice vampires, and the fathers of the apprentice vampires into his thralls. Soon one of Tirgov's thralls descends upon the Pikes and their friends to warn Jack that his efforts are useless.
