The Rapture of Cain. Theta Waves, #5

Sometimes immortals must face deathThe immortal Cain has awoken in the worst of places: a gothic-style church in the seediest parts of New Earth. Not only is he trapped there, but he's taunted by the hermaphrodite Sasha, who has plied him with godspit during his regeneration so that he's alone, claustrophobic, and hopelessly addicted to the newest strain of the drug. It seems the world has been thrown into even worse chaos now that Theda and Ezekiel have defeated the Beast.
It's bad enough finding himself alive in the city when he is protected by the hated God, but when the red general makes her entrance, he discovers even his immortality won't be enough to save him the wrath of his divine protector. the Theta Waves series is not for the faint of heart. It can be dirty, gritty, and downright sacrilegious, but those who like it, like it a lot.
