From #1 New York Times best-selling author Brad Thor comes a pulse-pounding thriller, featuring a new breed of counterterrorism operators. Just as skilled, just as fearsome, and just as deadly as their colleagues, Delta Force's newest members have only one thing setting them apart—their gender. Part of a top-secret, all-female program codenamed The Athena Project, four of Delta's best and brightest women are about to undertake one of the nation's deadliest assignments.
