In 2081, the United States is on the brink of collapse. As civil unrest rises and martial law looms, an ear-splitting trumpet blast shakes the Earth-and Yellowstone erupts. The power grid fails. Communication goes dark. And the world slips into chaos. But that's only the beginning. The trumpet was a reckoning-a warning of unleashed evil. In Farley, West Virginia, Avery Lucas watches it all unravel. Churches burn. Christians are executed. Children vanish into government reeducation centers. Avery's always known how to fight, but this is a war he doesn't understand. His wife, Ahrie, calls it the Apocalypse, and if she's right, then guns, grit, and muscle might buy time-but they won't stop what's coming. Because what's coming isn't just violent-it's unholy. As the line between good and wicked disappears, his family clings to their faith while Avery wrestles with doubt and a fear he can't outrun. He wants to believe. But first, he has to survive. And can belief really stop a bullet? Desperate to protect his wife and sons, Avery flees to the mountains, praying the wilderness can shield them. But as ungodliness spreads to every corner of the Earth, he's forced to confront the one enemy he can't shoot, stab, or escape: the war inside his soul.
