By the time anyone realizes what’s happening, it is too late. A dark network of hackers has infiltrated the computers of the U.S. military, unleashing chaos across the globe. U.S. missiles strike the wrong targets. Defense systems fail. Power grids shut down. Within hours, America’s enemies move in. Russian tanks plow through northern Europe. Iranian troops invade Iraq. North Korea destroys Seoul and fires missiles at Japan. Enter Jake Mahegan and his team. Their mission: locate the nerve center of ComWar—aka Computer Optimized Warfare—and shut down the operation through any means necessary. There are three ComWar headquarters, each hidden deep underground in Russia, Iran, and North Korea. Each contains a human biometric nuclear key that the team must capture to shut down the imminent nuclear strikes. Splitting up the team is Mahegan’s only chance to prevent the next wave of cyber attacks. But even that won’t stop the sleeper cell agents—here in the United States . . .
