Passenger by Flint Epstein

The cab drove on; else the void would overtake them. He passed mooks with chalky socks, and bitter dispositions, he passed hookers with red, claws gripping brown tufts of their rival’s hair, and he would never outrun them if his hands never touched the wheel.
Privy is a city located in the aft towage of the starship Aeolipile, unable to secure enough energy taxes to light the artificial sun; it is left in permanent night. A Griefer named Dire controls his turf without the usual strong-handedness dealt by the neighborhood kings; but as individual territories begin to shrink and the wars of the elite bleed on the headlines, Dire realizes his driver and the strange darkness of the cab can no longer shield him from the plans of the God Eater.
