The Zombie Wars : The Enemy Within

The Zombie Wars have been going on for nearly a year. John Talon and his army have been chasing zombies from one mountain range to the other, but there is another threat that lives in the wilds of the Rocky Mountains. A threat that, if turned loose, will forever change the future of the struggling New United States. John must face this menace head on, or lose everything his army has fought and died for.
