After running and gunning across much of the western US, Cade Grayson, former Delta Force operator, is finally reunited with his wife, Brook, and daughter, Raven. Hours after arriving at the relative safety of Schriever Air Force Base in Colorado Springs, the new Capital of the United States, Cade is approached by the new president, Valerie Clay. Her request is simple: she appeals to the patriot in him to rejoin the unit that he left for civilian life 15 months prior and once more go into harm's way, taking the fight to the enemy.
Meanwhile, Duncan Winters, Vietnam-era aviator, finds himself stranded in Springs along with BLM firefighter Daymon Bush. Both men arrived with Cade and were promised transport back to Eden, Utah. Duncan longs to be reunited in Eden with his brother, Logan, a survivalist/Doomsday prepper. Daymon, with no surviving family, knows only one thing for certain: he doesn't want to remain trapped behind the wire inside of a huge government-run military base.
