The world's number one terrorist is about to unleash a holy war. Only one agency, one man, can stop him . . .

The Campus was secretly created by President Jack Ryan to covertly eliminate terrorists. Now it faces its greatest threat: a sadistic killer known as the Emir. Mastermind of countless horrific attacks, the Emir has eluded capture by every law enforcement agency in the world. And he is about to unleash a monumental strike at the heart of America.

But on the Emir's trail is intelligence expert Jack Ryan Jr. Following in his legendary father's footsteps, he and his allies at the Campus are on a manhunt that will take them across the globe, into the shadowy arenas of political gamesmanship, in a race to prevent the fall of the West.
