THE ALL-NEW SUBMARINE ACTION SERIES

In the Cold War, nuclear submarines lead the fight. But the USS Squallfish is one of the old school - as is her skipper, Captain Chad Shipley. While on a routine patrol, he is ordered to infiltrate the heart of the Soviet Northern Fleet to spy upon the enemy's nuclear sub capabilities.

But the first Soviet nuclear sub is already under way, and has found its first prey - the Squallfish.
