As the world shakes from seemingly disparate outbursts of terrorism, Jack Ryan prepares for a crucial negotiation with President Zhou's increasingly hostile China. But when a routine traffic stop on an isolated road in rural Texas leads to the discovery of a stolen USB stick, it becomes clear there is a dark connection between the attacks. With tensions rising, a US spy ship in the South China Sea gets caught up in a violent storm - a storm which threatens to push it into the path of the Chinese navy, with potentially disastrous consequences. 

In an off-limits computer lab near Chicago, a mole infiltrates and steals a sophisticated piece of government security software. The implications are devastating - but it's only half the prize.... 

A US Navy commander is attacked by an unidentified Russian man while having dinner with his wife. A CIA operative travelling on a Canadian passport is intercepted and interrogated at Tehran Airport. A team of FBI officers are arrested by Indonesian police for travelling under fake passports in Jakarta. These apparently unrelated incidents point to a compromise in US government security, and Jack Ryan and his team must find out where it is coming from.

When brilliant and eccentric scientist Liu Wangshu disappears from his apartment in China, the Ministry of State Security is furious and certain they know what's happened: a defection to the Americans. President Jack Ryan knows how valuable an asset Liu would be - the inventor is responsible for much of China's recent technological progress, with his latest project rumoured to be the biggest yet. The problem is that none of Ryan's team have any idea where Liu is. 

On a break between missions, Jack Ryan Jr is asked by his mother to visit Sarajevo and track down a girl whose life she saved during the Bosnian War. Finally, he thinks, life might be quietening down. That's until he meets Aida - grown from a child into a beautiful and selfless woman. Jack finds himself drawn to her, not to mention impressed by her dangerous work helping Syrian refugees enter Europe. But the region is increasingly unstable, and just as Jack lets his guard down, Aida is violently kidnapped by the Serbian mafia.

Jack Ryan - out to avenge the murder of an old friend - finds himself in deep trouble fast...During a well-earned break, Jack Ryan Jr runs into old flame Renee Moore in a scenic Barcelona café. But Renee is not so pleased to see him. Distracted, she says she's waiting for someone and can't talk. She promises to call him later and sends him out onto the street. Which is when the bomb goes off. There's nothing he can do to save Renee. But as he cradles her, she utters one last word with her final breath: 'Sammler'. Who did she mean? What did she know? 

After a freezing mission in the North Sea which nearly costs lives - including his own - US Campus agent Jack Ryan Jr is taken off black ops. Ordered onto routine surveillance, he is sent to Singapore to check out a company with US interests. Soon enough, however, he finds the task anything but routine. It's clear there's a mole who must be uncovered - and quickly. As the mole attempts to cover their tracks, Jack finds himself dodging a team of highly trained killers as a tropical storm rolls in. What are the assassins trying to hide? And can Jack survive long enough to stop them?   

A North Korean ICBM crashes into the Sea of Japan. A veteran CIA officer is murdered in Ho Chi Minh City, and a package of forged documents goes missing. The pieces are there, but assembling the puzzle will cost Jack Ryan, Jr., and his fellow Campus agents precious time. Time they don't have.

Abandoned by other international leaders, Jack Ryan alone counters the threat posed by Russian president Valeri Volodin. This isn't the first time that the dictator has threatened world peace, but this time he's playing a very nuanced game, moving chess pieces around the board while isolating Ryan from the rest of the international community. Fortunately, Jack Ryan, Jr. and the rest of his Campus team find themselves in the middle of action with a vital clue to the Russian's intentions.

Decades ago, when he was a young CIA analyst, President Jack Ryan, Sr. was sent on what was supposed to be a simple support mission to investigate the death of an operative looking into the suspicious banking activities at a Swiss bank. Ryan’s dogged tenacity uncovered not only financial deceit, but also the existence of a KGB assassin code-named Zenith.

Dominic Caruso. Nephew of President Jack Ryan. FBI agent and operator for The Campus, a top secret intelligence agency that works off the books for the U.S. government. Already scarred by the death of his brother, Caruso is devastated when he can't save a friend and his family from a terrorist attack. Ethan Ross was a mid-level staffer for the National Security Council. Now he's a wanted fugitive on the run with a microdrive that contains enough information to wreck American intelligence efforts around the world.

Privately training with special forces, he’s honing his combat skills to continue his work within the Campus, hunting down and eliminating terrorists wherever he can--even as Jack Ryan Sr. campaigns to become President of the United States again. But what neither father nor son knows is that the political and personal have just become equally dangerous. A devout enemy of Jack Sr. launches a privately-funded vendetta to discredit him and connect him to a mysterious killing in his longtime ally John Clark’s past. All they have to do is catch him.

It is The Campus. Secretly created under the administration of President Jack Ryan, its sole purpose is to eliminate terrorists and those who protect them. Officially, it has no connection to the American government - a necessity in a time when those in power consider themselves above such arcane ideals as loyalty, justice, and right or wrong.

Charged with spotting terrorist threats, the top-secret "Campus" has its hands full when Middle East thugs and Colombian drug lords join forces. New Campus recruits include Jack Ryan Jr., son of master spy John Patrick Ryan, now President.

President Jack Ryan faces a world crisis unlike any he has ever known. A high-level assassination attempt in Russia has the newly elected Ryan sending his most trusted eyes and ears - including antiterrorism specialist John Clark - to Moscow, for he fears the worst is yet to come. And he’s right. The attempt has left the already unstable Russia vulnerable to ambitious forces in China eager to fulfill their destiny. If they succeed, the world as we know it will never look the same. If they fail, the consequences may be unspeakable.
