A near-future military experiment thrusts a multinational armada back to 1942, right into the middle of the US naval task force speeding towards Midway Atoll - and what was to be the most spectacular Allied triumph of World War II. The twenty-first-century sailors are a shocking spectre for these veterans of Pearl Harbor - men who have never seen a helicopter or a nuclear weapon, and who have never encountered an African American colonel or a female Australian submarine commander. But they respect the armada's awesome firepower, and what it may mean to the war. Initial jubilation is quickly doused by a shocking realisation - other ships may have made the trip - and may be in the hands of the Japanese. What happens next is anybody's guess...and everybody's nightmare.
