In the endless war between East and West, oil has become the ultimate prize. Nuclear-powered subtugs brave enemy waters to tap into hidden oil reserves beneath the Eastâ€™s continental shelf. But the last twenty missions have never returned. Have sleeper agents infiltrated the elite submarine service, or are the crews simply cracking under the pressure?
Psychologist John Ramsay has gone undercover aboard a Hell Diver subtug. His mission is to covertly observe the remainder of the four-man crewâ€”and find the traitor among them. Sabotage and suspicion soon plague the mission, as Ramsay discovers that the stress of fighting a war a mile and a half under the ocean exposes every weakness in a man. Hunted relentlessly by the enemy, the four men find themselves isolated in a claustrophobic undersea prison, struggling for survival against the elements . . . and themselves.
A gripping novel by the legendary author of Dune.
