When Eric Steele gets a call that a fellow Alpha is in serious trouble, he rushes to Paris. But it's too late - Ron Raines, Alpha Six, is dead, the victim of a brutal stabbing. While on leave in the City of Light, Raines had met an attractive art historian who lured him to his death. Before she vanished, the mysterious woman left a warning for anyone from the Alpha Program who might follow her. One of the best and most effective warriors in the U.S. military's top-secret Program, Steele has been trained to take on lethal enemies, and no threat will deter him from avenging a fallen brother. But the killer won't be easy to find. The search takes Steele across Europe, from Paris to a top-secret Russian prison to Syria, and finally back home to the streets of Washington, DC. No one is safe while the killer is on the loose, and the danger is heightened when Steele discovers intel that killing Alphas is just the beginning of a larger, more nefarious plot. The real target is much, much bigger - and it's up to Steele to prevent catastrophe before he becomes the next elite warrior to fall.
