When California’s Mojave Desert becomes the training ground for a homegrown militia group with a deadly scheme to "take back" America, Mack Bolan is sent in to unleash his own form of destruction. But first he’ll have to infiltrate the unit and unravel their plot before it’s too late.With less than forty-eight hours to go, the stakes have suddenly been raised and millions of Americans are about to be caught in the cross fire of a terrorist attack. As the militia sets its plan in motion, Bolan has only one opportunity to strike back and shut them down forever. Timing will be tight, but if these right-wing extremists want a war, then the Executioner is there to oblige.
