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?

"US intelligence says there's something going on in Russia. While their land forces have been decimated by corruption and incompetence, the Navy seems to be pouring money into some secret project. Analysts are stumped, until the knot is untangled by one particularly bright young woman at the Office of Naval Intelligence--Katie Ryan, the youngest daughter of President Jack Ryan. Like her father, she sees patterns where other don't, and she's determined that the Russians are about to launch a super missile sibmarine, the Belgorod. Now the race is on to determine where the sub is and whether it poses a threat to the continental US."--Provided by publisher.
