Decades ago, when he was a young CIA analyst, President Jack Ryan, Sr. was sent to investigate the death of an operative looking into suspicious activities at a Swiss bank. Ryan’s dogged tenacity uncovered not only financial deceit, but also the existence of a KGB assassin code-named Zenith. He was never able to find the killer.
But in the shadowy world of covert operations, nothing stays hidden forever.
In the present, when an old friend of the Ryans is poisoned by a radioactive agent, the trail leads to Russia. And Jack Ryan, Jr. — aided by his compatriots John Clark and the covert warriors of the secretive Campus — must delve into an international conflict thirty years in the making, and finish what his father started.
