It takes political intrigue—and plenty of tanks—to defeat zombies. Escaped zombies from behind The Wall have swept across the northeast, their path marked by havoc and death. Into this nightmare world are thrust several unlikely heroes. A full-time National Guard soldier leads his company of tanks on a harrowing journey towards the Appalachian Defensive Line. A small group of refugees fight for their own survival and end up facing demons of a different sort. A hero from the last zombie war must fight against the first invasion of the continental United States in over two hundred years. Retired CIA operative Asher Hawke, AKA the Kestrel, will stop at nothing to eliminate the zombie threat—and save the nation that he's dedicated his life to protect.
