Weapons of Choice - John Birmingham

On the eve of America's greatest victory in the Pacific, a catastrophic event disrupts the course of World War II, forever changing the rules of combat....

The impossible has spawned the unthinkable. A military experiment in the year 2021 has thrust an American-led multinational armada back to 1942, right into the middle of the U.S. naval task force speeding toward Midway Atoll—and what was to be the most spectacular U.S. triumph of the entire war.

Thousands died in the chaos, but the ripples had only begun. For these veterans of Pearl Harbor—led by Admirals Nimitz, Halsey, and Spruance—have never seen a helicopter, or a satellite link, or a nuclear weapon. And they've never encountered an African American colonel or a British naval commander who was a woman and half-Pakistani. While they embrace the armada's awesome firepower, they may find the twenty-first century sailors themselves far from acceptable.

Initial jubilation at news the Allies would win the war is quickly doused by the chilling realization that the time travelers themselves—by their very presence—have rendered history null and void. Celebration turns to dread when the possibility arises that other elements of the twenty-first century task force may have also made the trip—and might now be aiding Yamamoto and the Japanese.

What happens next is anybody's guess—and everybody's nightmare....

"This is an excellent combination of near future military SF and alternate history, and a riveting story to boot."
   ERIC FLINT, AUTHOR OF 1632 AND 1634: THE GALILEO AFFAIR

"This book has everying: time travel, the British royalty, things that go boom, and unrelenting action. Read the opening at your own risk: you won't be doing anything else until you finish it."
