ON THE 40 YEAR ANNIVERSARY OF THE HUNT FOR RED OCTOBER COMES A SUBMARINE THRILLER TO REMEMBER!

The #1 New York Times bestselling series returns to its roots...

For President Jack Ryan, it feels like deja vu. An advanced Russian submarine, the BELGOROD, has unexpectedly departed the Northern Fleet submarine base at the Arctic circle and is heading west. Is the Russian captain trying to defect like Marko Ramius did during the Cold War, or is a different gambit unfolding this time around?

Lieutenant Katie Ryan, following in her father’s footsteps, has just been promoted to senior analyst at the Office of Naval Intelligence (ONI) when she discovers that the BELGOROD is carrying Poseidon torpedoes. The Poseidon is Russia’s newest weapon of strategic terror—a nuclear powered, nuclear armed torpedo designed to create radioactive tsunamis that could render the US eastern seaboard uninhabitable. With unimaginable stakes on the table, father and daughter must outfox the Russian sub captain and find the rogue submarine before all-out war breaks out.
