The Gemini Factor

Mark Jensen lives in Duncan's Creek, North Carolina. His parents are murdered and his 15 year old twin sister is Kidnapped by a vicious Vampire called Denny Delmarcus the fifth.
Mark searches for his sister for 6 long years, not having a clue where she is.
He hears people of the town talking about a girl named Felicity Blue; he wonders if she is the sister he has been searching for. He leaves a message for her to get in touch with him and that he must see her. He gets a warning to stay away or everyone he loves will be in danger.
When his wife and son are brutally murdered, three years later, he goes searching for Felicity Blue, and finds out her whole persona is a Farce, and learns the location of her nest. He meets Detective Mel Stockard, and they take a team into the vampire's crypt, and learns that Denny is the one who killed his parents and kidnapped his sister, and to top that off, he learns of an original Polymorphic vampire named Count Vostro Greene who has the ability to morph into anyone he sees or touches.
Will Mark find his sister, and will he end the reign of Count Vostro Greene?
Having lost everyone he cares about, and the town under attack from a hoard of vampires, Mark and the team, a total of eight well trained men, go on a hunting trip with Mark at the lead. He is a blood descendant of a family of vampire hunters who have fought this vampire count across several centuries and two continents.
