Shadows of the City, book 1: The ArtfulWilbert Stanton2014

New York City, 2025: Everything is changed. The city that never sleeps is now a land of death and decay. A rampant virus has taken over and the survivors have become carriers, quarantined from the rest of the world.
Twist and Dodger grew up in the streets, the sewers and underground tunnels - their playground. They aren't heroes. They just like attention; and stealing meds from the rich and giving them to the poor is their golden ticket.
On their latest raid, they unknowingly steal a cure that puts them square between the ailing Emperor of Manhattan and the war hungry Governor of Brooklyn and forces them on a quest into the darkest shadows of their putrefying world.
