The Master's Bloodline (The Master's Bloodline Series: Book 1‪)‬

Despite the ability to see in the dark, fangs, and an all-consuming thirst for Vampire blood, Blaine LaShomb--paramilitary specialist, insists he's still human. Brash, quick-witted and brilliantly merciless, Blaine and his team of genetically-engineered soldiers kill vampires with the pride and skill of Hollywood surgeons. And with the decade-long war between humans and Vampires coming to a close, there is but one possible outcome: Within a year, the entire human race will be at the mercy of the vampires.
With his military unit completely wiped out and his career as a soldier far behind him, Blaine settles in a sleepy, West Virgina town where humans and vampires live together peacefully--until he quickly learns things may not be as bleak as they seem: Humanity may get one last shot at redemption.
Headed by a strong-willed half-human Dhampir named Lisette, the denizens of Harper's Ferry plot to infiltrate the Governing Body of Vampires. By assuming control of one of the most powerful Vampire Houses, humanity may be spared a life as little more than cattle. Reluctantly, Blaine takes up arms with his newfound allies while holding onto one simple truth: Vampires always turn on you.
