Tom Clancy Act of Defiance (Jack Ryan Book 24)

In the latest #1 New York Times bestselling Tom Clancy series, a rogue Russian nuclear submarine, the Belgorod, heads toward the U.S. East Coast, sparking global alarm.

As President Jack Ryan faces echoes of the Red October crisis decades earlier, U.S. intelligence races to uncover who controls the Belgorod and what devastating weapons it carries.

With fleets, jets, and SEALs ready for action, Ryan must rely on the next generation—including his own child—to uncover the truth. But when time runs out, he’s forced to make an impossible choice between protecting his nation or saving his family.
