"A thriller set at the height of the Cuban Missile Crisis"-- Provided by publisher.

1962. KGB Lieutenant Colonel Alexander Vasin is chasing the long-rumored existence of an American spy embedded at the highest echelon of Soviet power. Engaged in high-stakes espionage against a rival State agency, he first hears whispers of an ominous top-secret undertaking: Operation Anadyr. As tensions flare between Nikita Khrushchev and President Kennedy over Russian missiles hidden in Cuba, four Soviet submarines are ordered to make a covert run at the American blockade in the Caribbean--each sub carrying tactical ballistic missiles armed with thermonuclear warheads. The fate of the world rested with the itchy trigger finger of one lone Soviet naval officer, 100 meters under the sea, out of all contact with his commanders. -- Adapted from book jacket.
