Hunter Killer (Movie Tie-In edition)
Below the polar ice cap, an American nuclear submarine moves quietly in the freezing water, tailing a new Russian sub. But the usual, unspoken game of hide-and-seek between opposing captains is ended when the Americans hear sounds of disaster and flooding, and the Russian sub sinks in a thousand feet of water. The American sub rushes to help, only to join its former quarry in the deep.
The situation ignites tensions around the world. As both Washington and Moscow prepare for what may be the beginnings of World War III, the USS Toledo—led by young, untested Captain Joe Glass—heads to the location to give aid. He soon discovers that the incident was no accident. And the men behind it have yet to make their final move. A move only Glass can stop.
