Final Run

The Cold War is being fought on every front. Under the seas, the newest, most technologically advanced nuclear submarines are leading the fight while the old diesel engine subs are dying out. The USS Squallfish is one of the old school—as is her captain.
 
Captain Chad Shipley earned his stripes under the Pacific as Japanese depth charges exploded around him. Now, as he takes the Squallfish 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. Against a captain as clever and cunning as himself, Captain Shipley and the crew of the Squallfish must rise to the battle—or sink into the crushing depths.
