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, mapping our cities, learning our weaknesses, leaving tragedy in their wake. Our governments knew, but they did nothing - the prospect was too awful, the costs too high - and now, the horrifying and utterly alien Cray are invading, 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.
 
These are the three books that make up a trilogy that has been the product of many other books, thesis, and abstracts. It is a study in PTSD where the people are as real as they can be.
