Ice Island

Description for ICE ISLAND by Irving A Greenfield:

Deep beneath the frigid arctic seas, two awesome machines of destruction stalk each other in a deadly game of hide-and-seek. One is the new super-high-tech breed of American submarine, the S99, under the command of Admiral Jack Bower. The other is a Soviet killer sub, determined to prevent the S99 from carrying out its mission, regardless of the cost.
