Bloodsuckers - Michael A. Ventrella

Norman Mark was a politician with skeletons in his closet. Literally.

Disgraced journalist Steven Edwards considers the "Batties"-the loonies who believe that vampires are real and Norman Mark is one-just another crazy tin-foil-hat extremist group. Then someone shoots at Mark, changes into a bat, and flies away before Steve's eyes, leaving him as the prime suspect. With the help of the Batties, Steve goes underground. The only way he can establish his innocence is by proving vampires exist-not an easy task while on the run from both the FBI and the bloodsuckers.
