Jack Ryan Jr.--along with the covert warriors of the Campus--continues to uphold his legendary father's legacy of courage and honor in this thriller from #1 New York Times bestselling author Tom Clancy.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.
