Tom Clancy Act of Defiance (A Jack Ryan Novel Book 24)

A rogue Russian nuclear submarine is heading toward the U.S. East Coast, and for President Jack Ryan, the haunting memories of past crises are now overshadowed by the very real dangers facing the nation in this latest addition to the #1 New York Times bestselling series.

U.S. intelligence reports chaos within the Russian navy, with their most lethal submarine, the Belgorod, unexpectedly launched. But questions abound: Who ordered its departure? What is its mission? And perhaps most troubling—what deadly secrets are hidden within the submarine’s giant bow doors?

It’s been forty years since a similar crisis involving the Soviet submarine Red October, which was resolved by a young CIA analyst named Jack Ryan.

Now, as President, Jack Ryan commands fleets, fighter jets, and SEAL teams, but crucially, he lacks insight into the Belgorod's plans. It’s up to the next generation of Ryans to undertake the perilous task of uncovering the submarine’s intentions.

However, every decision comes with a cost. As time runs out, Jack Ryan will face a heart-wrenching choice between protecting his country and safeguarding his child.
