The Great War

Harry Turtledove's Great War saga plunges us deeper into the war that began in Europe, then exploded with a vengeance onto American soil.
The world is convulsing. Germany has smashed its enemies: Austria, Denmark, and France, while the United States and the Confederate States of America charge headlong into the global conflict - as bitter enemies once again.
The year is 1915, and the time of darkness has come. Though the Confederacy has defeated its northern enemy twice in fifty years, this time the United States has allied with Prussia. In the South, the freed slaves, fueled by Marxist rhetoric and the bitterness of a racist nation, take up the weapons of the Bolshevik rebellion. Despite these advantages, the United States remains pinned between Canada and the C.S.A., so the bloody conflict continues and grows. Both presidents - Theodore Roosevelt of the Union and staunch Confederate Woodrow Wilson - are stubbornly determined to lead their nations to victory, at any cost.
While land and sea battles are fought around the globe, new killing tools - poison gas, submarines, attack planes, and tanks - are pressed into service. Heroism and fear run hand in hand as ordinary men and women - families, friends, and lovers - choose desperate measures just to survive.
Once again, Harry Turtledove has created a portrait of how, if history had but taken another path, our world would have launched into a much bloodier War to End All Wars.
