John Clark

His work for the CIA is brilliant, cold-blooded and efficient, but who is he? In a harrowing tour de force, phenomenally best-selling author Tom Clancy shows how an ordinary man named John Kelly crossed the lines of justice and morality to become the CIA legend known as Mr. Clark. It is an unforgettable journey into the heart of darkness, without mercy - without remorse.

Ex-Navy SEAL John Clark is the newly named head of Rainbow, an international task force dedicated to combating terrorism. In a trial by fire, he must stop a terrorist group of men and women so extreme that their success could literally mean the end of life on earth as we know it.
