The old rules no longer apply - anybody with a spare AK47 or a knowledge of kitchen chemistry can become a player. In a nondescript office building in suburban Maryland, 'The Campus', set up with the knowledge of President John Patrick Ryan identifies and locates terrorist threats - then deals with them, in whatever manner is necessary. It's an organisation always on the lookout for new recruits - men like Jack Ryan Jr, the President's son. Filled with the exceptional realism and cutting-edge authenticity that are his hallmarks, this is Clancy at his best - and there is none better.
