Red Death - Being the First Book in the Adventures of Jonathan Barrett, Gentleman Vampire
In this introduction to the series, young Jonathan Barrett arrives in London in 1773 to pursue his college education. His fate among the undead is sealed by the unnaturally beautiful Nora Jones, who seduces him and consumes his blood. Unbeknownst to Jonathan, he is no longer the same man, something he soon discovers upon his return to America to join the armed forces and defend his country. Rather than an appetite for traditional fare, he has developed a strange craving for human blood.
