Grunt Life (A Task Force Ombra Novel Book 1)

THE INVASION IS OVER. THEY ARE ALREADY AMONGST US.
Benjamin Carter Mason died last night. Maybe he threw himself off a bridge into Los Angeles Harbor, or maybe he burned to death in a house fire in San Pedro; it doesn’t really matter. Today, Mason’s starting a new life. He’s back in boot camp, training for the only war left that matters a damn.
For years, their spies have been coming to Earth, learning our weaknesses. Our governments knew, but they did nothing—the prospect was too awful, the costs too high—and now, the horrifying and utterly inhuman Cray are laying waste to our cities. The human race is a heartbeat away from extinction. That is, unless Mason, and the other men and women of Task Force OMBRA, can do anything about it.
This is a time for heroes. For killers. For Grunts.
