When a rogue state tries to go nuclear, only two men can stop it .
. . Jack Ryan Jr is in Ho Chi Minh City tailing an ex-CIA operative
with valuable documents when a hit leaves Jack with a corpse, no
documents and only a bloodily scribbled note as a clue to what just
happened. It sends him on the trail of a shadowy security firm with
links to North Korea, newly resurgent under its young, power-hungry
dictator. For the rogue state has found a way to finally make its
nuclear ambitions a reality - no matter the cost to the world. This
is something President Jack Ryan will not permit - but North Korea
and its backers have plans for US leader which will silence him for
good. On the ground and on the global stage, Jack Ryans Jr and Sr
race against time to halt a madman from acquiring the world's
deadliest weapon . . .
