The Priest of Blood
By Douglas Clegg, 2005
Series: The Vampyricon

"The man known as Falconer was born the bastard son of a whore, served the royal court as a predator trainer, and warred against the infidel Saracens as a conscripted soldier in the Holy Land. But it wasn't until he found himself in the arms of a creature called Pythia that he found his destiny-as a vampire."
