What Remains — Juli Valenti

It happened so fast, it spread through the world like wildfire. It was impossible to control and almost impossible to fight... Ten years has passed since an infectious virus nearly consumed all of mankind. Millions died, millions more became infected, changed, became mindless, feral hunters bent on the consumption of living flesh. Archer was a solitary man, scavenging what he could to survive off the ruins of the world that no longer existed. A world gone mad, where those who still lived were just as great of threat as those who were infected. Without knowing it he finds himself in possession of a map that leads to a hidden sanctuary with the possible means to stop it all. All he has to do, is get her there alive...
