Tom Clancy's Jack Ryan: Ghost War is out now on Prime Video!

A rogue nuclear Russian submarine is steaming toward the East Coast of the United States. For President Jack Ryan, memories of past events may seem stunningly vivid, but the dangers are terrifyingly real in the latest entry in this #1 New York Times bestselling series.

US intelligence is reporting turmoil in the Russian navy. Their deadliest submarine, the Belgorod, has unexpectedly launched, and taken along with it a long list of questions. Who authorized the departure? What mission is it on? And, most disturbing of all, what weapons do the giant doors on the sub’s bow hide?

It's been four decades since a similar incident with the Soviet sub, Red October, ended happily, thanks to a young CIA analyst named Jack Ryan.

Now, President Jack Ryan finds himself with fleets of ships, squadrons of jets, and teams of SEALs at his command, but what he doesn’t have is insight into the plans of the Belgorod’s commander. It falls to a younger generation of Ryans to do the dangerous work that will reveal that information.

But there’s always a price to be paid. When the final moments tick away, will Jack Ryan have to choose between the safety of his country and the safety of his child?

Thirty-five years ago, Tom Clancy was a Maryland insurance broker with a passion for naval history. Years before, he had been an English major at Baltimore’s Loyola College and had always dreamed of writing a novel. His first effort, The Hunt for Red October, sold briskly as a result of rave reviews, then catapulted onto the New York Times bestseller list after President Reagan pronounced it “the perfect yarn.” From that day forward, Clancy established himself as an undisputed master at blending exceptional realism and authenticity, intricate plotting, and razor-sharp suspense. He passed away in October 2013.
