Jack Ryan (chronological order) (abridged)

Being President doesn't make things any easier, Jack Ryan finds out, especially when trouble's brewing in Moscow and China. Blending the exceptional realism and authenticity that are his hallmarks with intricate plotting, razor-sharp suspense, and a remarkable cast of characters, this is Clancy at his best - and there is none better.

It is The Campus. Secretly created under the administration of President Jack Ryan, its sole purpose is to eliminate terrorists and those who protect them. Officially, it has no connection to the American government - a necessity in a time when those in power consider themselves above such arcane ideals as loyalty, justice, and right or wrong.

Privately training with special forces, he’s honing his combat skills to continue his work within the Campus, hunting down and eliminating terrorists wherever he can--even as Jack Ryan Sr. campaigns to become President of the United States again. But what neither father nor son knows is that the political and personal have just become equally dangerous. A devout enemy of Jack Sr. launches a privately-funded vendetta to discredit him and connect him to a mysterious killing in his longtime ally John Clark’s past. All they have to do is catch him.
