The best place to be in an Apocalypse is inside a thirty ton Bradley Fighting Vehicle grinding rotting bodies to paste under your tracks or using an Abrams 120mm canister round to turn a horde of undead into a pink mist. Here's the thing though ... tracks and guns and the people who operate them wear out, even as the living corpses keep coming at you. After a brutal summer of combat in the plains and cities of the Midwest, the First Infantry Division is conducting a fighting retreat back to the Pacific Northwest. Both the winds of Fall and the howls of the undead are echoing in their wake when they're re-tasked to take Denver Airport. Along the way they have to safeguard thousands of civilians who are following in their armored wake, and one mistake can turn them all into a ravening horde. For Staff Sergeant Mark Foley and his tired mechanized infantry squad, it means diving once more into the hell of combat against both raiders who will shoot you dead for a gallon of gas and infected that will send you to a special kind of living death. The third volume of Shane Gries' best selling, "The Line" series.
