A powerful banker, gunned down in cold blood. A military family, senselessly slaughtered as they sleep. A four-star general, hacked and framed by virtual assassins. When Jake Mahegan receives a distress call from General Savage in North Carolina, he rushes to the commander's home-- and walks right into an ambush. Joining forces with Savage's combat JAG officer, Alexandra Russell, Mahegan follows the trail to a killer who goes by the name "Jackknife," a Syrian refugee-turned-terrorist who vows to avenge the bombing of a Syrian wedding. Terrorist cells are gathering in the Blue Ridge Mountains. Hackers are emptying the nation's banks of millions of dollars. And their final act of vengeance will bring the whole world to its knees.
