Featuring John Clark, the ex-Navy Seal known from several of Clancy’s novels, as the dark side of Jack Ryan, this is Tom Clancy’s new and most extraordinary novel. John Clark is the man who conducts the secret missions President Ryan can have no part of. Whether hunting warlords in Japan or druglords in Colombia, Clark is efficient and deadly but even he has ghosts in his past. And nowhere more than the peril he must face in Rainbow Six: a group of terrorists the world has never encountered before. This is Tom Clancy’s most shocking story ever – closer to reality than any government would care to admit.
