2037: Every nation wants underwater territory, and the race for resources on the ocean floor is on. World War III will be the war of the submarine. Alex Coleman is pretty sure that heroes don't explode coffee creamer fireballs and hijack cruise ships, but he uses the tools he's got. He's also certain they don't end up with a boat old enough to drink and his crew a few beers short of a six pack. No one expects him to make a difference...until the enemy gets a vote. Updates Sundays.
