In this third installment of the Zombie Crusade series, former army ranger Jack Smith and his younger brother have been reunited at Jack's fortified castle in Indiana. Even though Jack and his best friend, Carter Wilson, had spent 10 years preparing for the virus they had once encountered in Afghanistan, when the outbreak came the apocalyptic nightmare was even worse than they had imagined. Now Jack and his allies know that the flesh-eaters aren't actually zombies, but rather living organisms evolving into deadly predators that the humans had come to call hunters. Gradually, Jack and his followers set out to establish a network of survivors from the Rockies to the Great Lakes. What had been a tiny resistance movement near a small town in Indiana begins to morph into a national struggle against ever-increasing hordes of flesh-eaters. Medieval weapons and modern armor still prove to be the most effective defense against the creatures in combat, even as the monsters evolve into stronger and more efficient killers. As humanity struggles to survive, one young man continues to exhibit an uncanny sixth-sense about the infected and a burning desire to rid the globe of the creatures he considers to be Godless abominations in a holy war between good and evil.
