Dark Ages: Setite

Fourth of the Dark Ages Clan Novels
Andreas has an offer for the vampires fleeing the destruction in thirteenth-century Constantinople: a way out of the East and passage to the safer lands of Western Europe. But Andreas is not just a merchant, he is a priest of the snake god, a Follower of Set intent on uncovering the heretics in his own clan. If certain refugees need to be sacrificed for that to happen well, such is the cost of faith.
