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. 

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. 

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.

On a crowded tourist beach in Portugal, US operatives use a high-tech drone to watch a French arms dealer flirt with a beautiful woman. It's only when she leaves that they realise she has shot him dead. In Iran, protests are growing against the oppressive regime, whipped up by a charismatic student. Most external observers are excited, but on the ground a spy of questionable loyalty senses something is badly amiss. 

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? 

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.

CIA analyst Jack Ryan, historian and former Marine, is vacationing in London with his wife and young daughter. Suddenly, right before his eyes, a terrorist group launches its deadly attack. Instinctively, Jack dives forward to intervene. By his impulsive act, he gains both the gratitude of a nation and the enmity of its most dangerous men who will not sit on their hate. In an explosive wave of violence, Jack's new enemies will seek to make him pay for his act of salvation...with his life.

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.

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.
