Knights of the Darkness by Nick Lewis

[Knights of the  Darkness]Book One of the Slayer Archives. Malcolm BonLore is a young cadet at the Air Force Academy, with a promising future. He is well on his way to becoming a fighter pilot and is very much in love with his girlfriend, whom he is about to propose to. He appears to have the world by the tail, but little does he know that in one night his world will be turned upside down and the path that he is following will develop a big detour. He will be asked to join a highly secret and very exclusive organization that has been around since the time of Christ; an organization whose members call themselves blood centurions and combat an evil that is even older than their organization-that of vampires. But before he can become a full-fledged centurion, he must deal with a renegade vampire who may be the source of his twist of fate.
