Eighty years into the future, the United States is a no-man’s-land: its landscape blighted by chemical warfare, pollution, and plague; its government collapsed; its citizens adrift, desperate, fighting to stay alive. In fortified compounds, survivors hold the line against wandering predators, rogue militias, and hideous mutations spawned from the toxic environment, while against them all stands an enemy neither mortal nor merciful: demons and their minions bent on slaughtering and subjugating the last of humankind. But from around the country, allies of good unite to challenge the rampaging evil.
