Dead City, livre audio

Jon Gilligan is the only living man in a city of the undead.
It’s his job to maintain order between the factions of walking corpses and disembodied spirits.
The workload has been driving him a little insane, leading him to take on the persona of a noir detective. He narrates his adventures, casting himself as a hero to all those under his watch.
But soon, it’s time for him to be a hero for real. Teaming up with a ghost and a woman they both love outside the walls, it’s up to the three of them to save Dead City from itself.
