Good Vampires Go to Heaven

Two-thousand-year-old vampire demon Zeb is supposed to spend eternity turning mortal sinners into bad guy Lucipires like himself.

But Zeb is a bad boy in a good way-secretly working as a double agent for none other than St. Michael the Archangel in hopes of one day earning his wings. Problem is, Zeb's betrayal is discovered.
