THEM: Invasion, Book 0

Aidan "Scratch" Sullivan is a former army ranger and Afghanistan War vet trying to achieve some semblance of normalcy while he deals with the psychological aftereffects of two combat tours in the 'Stan.

But when the bombs fall and the dead walk, Scratch is forced to risk life and limb to rescue his aging parents before zombies overrun their quiet community. And to do it, he'll need to traverse half the state of Texas while dealing with out-of-control military units, violent redneck looters, and all manner of evil things that go bump in the night.
