Locked On: Clancy, Greaney

Though his father had been reluctant to become a heroic field operative, Jack Ryan, Jr. wants nothing more…
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.
With Clark on the run, it's up to Jack, Jr. to stop a growing threat emerging in the Middle East, where a corrupt Pakistani general has entered into a deadly pact with a fanatical terrorist to procure four nuclear warheads they can use to blackmail any world power into submission-or face annihilation.
