A global race against the clock . . .

The Chinese Navy is gaining power. With quieter submarines carrying ballistic missiles, they pose a critical threat to President Jack Ryan's America. And behind their progress is just one man: eccentric scientist Liu Wangshu.

So when Liu goes missing, China suspects America's involvement. What's worse, President Jack Ryan discovers that a mole, code-named SURVEYOR, has infiltrated US intelligence to terrifying depths. Now more than ever, he needs the Chinese intelligence that Liu has to offer.

With the help of old ally John Clark and the Campus team, Ryan faces a double race against time. First, beat the Chinese government in a global hunt for Liu. Then scour the elite ranks of the CIA for SURVEYOR.

The heat is rising in this new Cold War . . .
