Mark Castillo, captain of the submarine USS Pasadena, is tracking a brand new Russian missile submarine when sudden disaster tears him away from his quarry. Pasadena’s sonar watch has just detected a massive casualty aboard a Russian Victor-class fast attack—and the enemy boat is going down. Castillo races to the scene to help rescue the trapped sailors. He speaks with the desperate commander of the lost submarine—and is haunted by the Russian boat’s DEEP WHISPER.
Castillo will do just about anything to pull those sailors off the bottom, but the Russian government refuses his help—leaving him with a terrible dilemma.
Will he risk everything to help—or will he let his fellow submariners die?
