A catastrophic earthquake ravages Afghanistan, and American troops rush to deliver aid, among them Afghan Air Force adviser Lieutenant Colonel Michael Parson, and his interpreter, Sergeant Major Sophia Gold. The devastation facing them is like nothing they ve ever seen, however and it s about to get worse. A Taliban splinter group, Black Crescent, is conducting its own campaign shooting medical workers, downing helicopters, slaughtering anyone who dares to accept aid. With the U.S. drawing down and coalition forces spread thin, it is up to Parson, Gold, and Parson s Afghan aircrews to try to figure out how to strike back. But they re short of supplies, men, experience, and information and meanwhile the terrorists seem to be nowhere . . . and everywhere."
