Mitch Rapp is a gifted college athlete who seeks retribution for the Pan Am Lockerbie attack. He trains intensely for six months with other clandestine operatives under CIA Operations Director Thomas Stansfield and protégé Irene Kennedy to stop terrorists before they reach America. Rapp leaves a trail of bodies from Istanbul across Europe to Beirut, where he must use every ounce of skill and cunning to survive the war-ravaged city and its deadly terrorist factions.
