Templar's Fire, a Gothic Vampire Novel

Abandoned in the Egyptian desert to die an infidel's death, mortally wounded Templar Knight Edwin Blutleer is rescued by an inhuman succubus. When his Templar comrades return to collect his corpse, they are stunned to find Blutleer alive, healed, and enraged. They betrayed the Templar Code: never leave a wounded brother behind. And he slaughters them to a man -- except one, who escapes. He is Blutleer's own cousin Pierre DeVeze. For 600 years, the immortal vampire Edwin Blutleer hunts and destroys the survivor's offspring and their heirs. Several generations change surnames and delay Blutleer, but he cannot be stopped.
