GRAYS roam the land, largely in the absence of human interference. Animals spontaneously transform into twisted, violent beings. The earth decays, collapsing into a network of abysses. The wilderness thickens.
It has been nine years since That Day when it all started. Pockets of humanity still exist, but are ignorant of one another. Within these isolated havens people try to live as best they can -- for even in a world so broken and dark, daily life must go on.
Darrell and Mary Williams were able to build such a life inside a five-acre fenced yard out in the country. They were even secure enough in their isolated haven that they had a daughter five years after the zombie-like grays appeared.
But another refugee is on the run with her six-year-old son, after the collapse of the compound in which she had lived. She doesn't survive, but her son is taken in by the Williamses -- who do not realize that this kind action will destroy their home and threaten their entire family.
