Book excerpt: From the USA Today–bestselling authors of Stand Your Ground comes the explosive story of a liberal college under siege—and freedom under fire. Former Army Ranger Jake Rivers is not your typical Kelton College student. He is not spoiled, coddled, or ultra-lib like his classmates who sneer at the “soldier boy.” But regardless of his differences with the rest of the student body, he needs an education. And when terror strikes, the school needs Jake. Without warning, the sounds of gunfire plunge the campus into a battle zone. A violent gang of marauders invade the main hall, taking students hostage for ransom. As a veteran and patriot, Jake won’t give in to their demands. But to fight back, he needs to enlist his fellow classmates and school them in the not-so-liberal art of war. This time, the aggression isn’t “micro.” It’s life or death. And only the strong survive.
