When Jack Ryan Jr, on a highly secret, off-the-books Campus mission in Turkey, discovers that his team s every move is monitored, he knows that US intelligence has been fatally compromised.

Back in the States, President Ryan watches in horror as China s weakened leader bends to a war-mongering general intent on turning the East into a bloodbath. At the same time, America comes under cyber attack from China, crippling government and military infrastructure. President Ryan needs to act: a covert team must go in and neutralise these threats, and the Campus is the perfect fit.

Except a sinister figure known only as the Center is watching the Campus and Jack Ryan Jr s every move. Any misstep will be their last . . .

Jack Ryan is back and he s got everything to play for in Tom Clancy s masterful Threat Vector. The Jack Ryan Jr series also includes The Teeth of the Tiger, Dead or Alive and Locked On.
