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.

For decades, Taiwan has been a thorn in the side of the Chinese government. New Chinese President Li Jian Jun has devised a secret military operation to take the island. Only Minister of Defense Qin Haiyu knows how to stop Li’s mad and bloody plan for reunification. Fearing for his life and the safety of his family, Qin covertly makes contact with the CIA in Beijing and signals his desire to defect to the West. To get Qin out, John Clark creates an international task force reminiscent of Rainbow Six and goes undercover in mainland China. Meanwhile, Lt. Commander Katie Ryan is deployed to the tip of the spear on the destroyer USS Jason Dunham to defend Taiwan. Threatened by an encircling Chinese armada, she’s under pressure to find a flaw in the invaders’ plan for her father to exploit. President Jack Ryan needs Li’s secret plans from Qin so he can stave off a war.

Secretary of State Frank Malone has been kidnapped from his Cairo hotel --- his security detail wiped out. President Natalie Cohen is left with several unacceptable options. It's time to think outside the box, and that can only mean one thing: the revival of the Presidential Agent program. Cohen calls for Charley Castillo to come out of retirement to direct a new Presidential Agent, one Captain P. K. "Pick" McCoy, USMC. Charley may be too old to kick down doors and take names, but Killer McCoy is just the man to get the job done. Together, they will track the kidnapped secretary from Cairo to sub-Saharan Africa. The only problem is that one man can't hope to win against an army of terrorists. Good thing there are two of them.

Nothing stops former Navy SEAL and Tier One operator John Dempsey from answering the call of duty --- including a mission with the highest stakes he’s ever faced. When one of the most brazen and lethal acts of terrorism rocks American and Israeli intelligence forces at the highest levels, Dempsey’s ultracovert antiterror unit, Ember, mobilizes. But this operation isn’t just a retaliatory strike by Ember; it’s a mission of vengeance for Dempsey --- against the Iranian terrorist mastermind who slaughtered Dempsey’s Tier One comrades. Racing from Tel Aviv to Tehran, the elite American warrior and his formidable Israeli counterpart must forsake their backup in a capture-or-kill gambit that could turn into a suicide run.

John Dempsey, former Navy SEAL and Tier One operator, is back. Only a few months into his new life as an operative for Ember, the United States’ most covert counterterrorism entity, he must stop an old nemesis who has resurfaced after 10 years of operating in the shadows. From the deserts of Iraq, through the jungles of Guatemala, to the streets of suburbia, Dempsey and his Ember team race against time to stop a series of horrific and devious attacks against the homeland.

John Dempsey’s life --- as an elite Tier One Navy SEAL named Jack Kemper --- is over. A devastating terrorist action catapults him from a world of moral certainty and decisive orders into the shadowy realm of espionage, where ambiguity is the only rule. His new mission: hunt down those responsible for the greatest tragedy in the history of the US Special Ops and bring them to justice. But how does a man torn between duty and revenge walk the line and preserve his soul? As Dempsey struggles with the games of spies, the case propels him across the globe in a desperate effort to prevent a new, horrifying attack on American soil.
