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.

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 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.

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. 

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.

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. 

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.

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.

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.... 

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.

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.

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.

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.

Tom Clancy returns to Jack Ryan's early days, in an extraordinary new novel of global political drama. Ryan's first days on the job at the CIA put him into a high-stakes game, playing for the life of the Pope and the stability of the Western world.
