In the fourth installment of the Zombie Crusade series, Jack Smith's Indiana settlement has become a target for General Matthew Barnes and his vast army of ever-evolving "hunters." Jack and the other leaders of the resistance decide to go on the offensive, first by travelling south to destroy bridges along the Ohio River. Will full support from the confederation in Utah, as well as valuable new allies, Jack's forces devise a nearly-suicidal plan to eliminate Barnes' main army of monsters by luring the mad general to a decisive battle at historic Vicksburg. As the fighting escalates, David is torn about the need to divulge an explosive family secret that could change the lives of Jack and Luke forever when forever might not last much longer than twenty-four hours. Back in the Midwest, Father O'Brien scours parts of the Great Lakes for potential hideaways in case Barnes can't be stopped, and he begins to befriend a group of wary Canadians on an island in Lake Huron. Meanwhile, Doc Redders makes a startling discovery about the virus that turns ordinary people into flesh-eating monsters.

Zombie Crusade Snapshots are quick glimpses of critical locations around the world as the zombie pandemic begins to unfold. While the snapshots connect to the main storyline of the Zombie Crusade novels (some in obvious ways, others in ways that will become apparent as the series continues), they may also be read as stand-alone stories. Two of the tales in this collection, "Israel" and "Ontario," have been previously released electronically. This volume includes: "Israel" An Israeli professor brings back more than artifacts when he returns home from an archeological expedition in the Hindu Kush Mountains. "Ontario" As the bizarre zombie pandemic sweeps across North America, residents of a large island on Lake Superior prepare to isolate themselves from the rest of the world. "POTUS" General Mathew Barnes ingratiates himself with the President of the United States in the early days of the global disaster. "Maine" A community of the super-rich hire the best protection money can buy to avoid being overrun by scores of infected as well as hordes of frightened citizens in search of a safe haven in their crumbling world. "Tennessee" An organized and self-sustaining settlement has to choose between the lesser of two evils when faced with an army of evolving, flesh-eating monsters.
