A Jack Ryan Novel (chronological order)

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.

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.

Jack ryan returns in this high-octane twenty-third instalment of Tom Clancy's heart-pounding, #1 New York Times bestselling series.
