The Collapse Trilogy

 A society in decay is a more dangerous place than a society under attack. The earth was dying it's natural resources have been used up. Countries have fallen into ruin. Only City States populated by the elite remain.  

Around the City States, a majority of the population scrounged through the ruins of the civilization to scrape out an existence. Between these two extremes was Vin Tanner, and his Resource Security Force team's job was to make sure the remaining natural resources were equitably divided between the haves and have nots. To keep the gangs in the Wild Areas at bay. Now Vin and his team were running for their lives as a Corporation Special Action team chased them through the ruins.

The seas were empty of all life. The Midwest was a desert. The western states fought wars over water as coastal cities sank under rising sea levels. What food was left was hoarded by the wealthy living lavish lives in the city states while those around them starved. Vin Tanner and the others in his settlement survived by scavenging the urban waste lands around the cities. There was no law except survival of the fittest in a civilization on the verge of collapse.

Vin Tanner and the rest of the small community he led had to flee.

A pandemic unlike any before was about to take place. They will have to fight their way through the ruins of a collapsing society to reach safety.

Roving gangs, people fleeing the sickness, and other unexpected dangers await them.

With what was left of the world collapsing around them, they had to find a new safe haven to survive.
