David McAfee: Bachiyr series

33 A.D. (Bachiyr, Book 1)

Jerusalem, 33 A.D. The vampires of the era have long sought to gain a foothold into Israel, but the faith of the local Jewish population has held them in check for centuries. When one of their own betrays them to follow a strange young rabbi from Galilee, the elders of the vampire race dispatch Theron, a nine hundred year old assassin, to kill them both. The rabbi's name is Jesus. Killing him should be easy.

AFTER - Taras and Theron: Beyond Jerusalem (Bachiyr #1.5) 

Containing the following short stories: 

Taras - Unable to bring himself to feed, Taras stumbles into Antioch. Tired, weak, and nearly broken under the weight of his guilt, he wanders the streets waiting for death to catch up to him. But when he is beset by bandits, he gains a new perspective. Maybe he doesn't have to feel guilty about feeding, after all. 

Theron - Theron travels by ship to his long ago home of Athens, Greece. He soon discovers the Council of Thirteen has put a price on his head so large every Bachiyr in the city will try to collect it, which leads to a very tense reunion with an old lover. 

61 A.D. (Bachiyr, Book 2)

Britannia, 61 A.D. For ten years, Taras has lived in the young city of Londinium, feeding off the city’s underbelly. But now Theron, his old enemy, has come looking for revenge, and Taras’ nights of living in relative peace are about to end. Yet not even Theron can slip into town unnoticed, and the Council of Thirteen sends Ramah to deal with the two renegades once and for all. But unknown to the Council, a much older enemy is also in Londinium, and this time even the great Ramah might not be safe. Set against the backdrop of the Iceni uprising in Roman-era Britannia, 61 A.D. continues the story of Taras, Theron, and Ramah, as they fight their way through history.
