Patriot Games is filled with the exceptional realism and authenticity that distinguished Tom Clancy's previous bestsellers. This novel places us on the cutting edge of a different type of war — the international battle of terrorism.

It is fall. Years before the defection of a Soviet submarine sends him hurtling into confrontation with the Soviets, historian, ex-Marine, and CIA analyst Jack Ryan is vacationing in London with his wife and young daughter. Suddenly, a terrorist attack unfolds before his eyes. Instinctively, he dives forward to break it up and is shot.

Upon waking in the hospital, he learns whose lives he has saved — the Prince and Princess of Wales and their new young son — and which enemies he has made — the Ulster Liberation Army, an ultra-left-wing splinter of the IRA.

By his impulsive act, Jack Ryan gains both the gratitude of a nation and the enmity of its most dangerous men — men who do not sit on their hate. In the weeks and months to come, Jack Ryan and his family become the targets of that hate.
