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.... 

On a remote island off the coast of Argentina, a team of elite counter-terror commandos prepare to assault a newly discovered Hezbollah hideout. What they don't expect is to be brutally ambushed themselves - slaughtered with no survivors. What they don't realise is that, on screens around the world, the enemies of the West are watching. Back in Washington, DC, the growing obstruction in the Senate has reached crippling levels, as a crucial treaty to strength NATO in Eastern Europe is inexplicably blocked.

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.

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.

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?   

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? 

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.

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.

America is under attack from within. Patients in hospitals, clinics and at home are dying when the drugs they need for survival turn out to be ineffective copies. A corrupt pharmaceutical billionaire has spent millions supporting radical groups while using the chaos they engender to cover his money-making schemes, but for a man with such towering ambitions, the only real goal is power. To get that, he'll have to eliminate the only impediment in his path - Jack Ryan.

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.

Jack Ryan Jr is on a simple job. An all-expenses paid trip to Israel in exchange for a of couple hours easy work, reporting back to an old friend at the CIA. What could be easier?Jack is here merely as an observer, but as he settles into his work in the market, he sees the glint of a knife, and throws himself in front of a woman and her young son under attack. Cover blown, he finds himself the target of trained killers. Alone and outgunned, Jack will have to use all his skills to protect the life of the child.

The Campus has been discovered. And whoever knows they exist knows they can be destroyed. Meanwhile, President Jack Ryan has been swept back into the Oval Office - and his wisdom and courage are needed more desperately than ever. Internal political and economic strife has pushed the leadership of China to the edge of disaster. And those who wish to consolidate their power are using the opportunity to strike at long-desired Taiwan, as well as the Americans who have protected the tiny nation.

Jack Ryan, Jr. is in Seoul to interview a potential addition to the Campus. But his benign trip takes a deadly turn when a wave of violence perpetrated by North Korean operatives grips South Korea's capital. A mysterious voice from North Korea offers Jack a way to stop the peninsula's rush to war, but her price may be more than he can afford to pay.

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.
