The Great War Breakthroughs by Harry Turtledove

These excerpts plunge into an alternate history where the American Civil War concluded differently, leading to a continued struggle between the United States of America (USA) and the Confederate States of America (CSA) in a global conflict paralleling World War I. The narrative is rich with personal stories from diverse perspectives, including soldiers from both sides, a newly elected Socialist congresswoman, a Québécois farmer caught between American and British influence, a former enslaved man turned revolutionary, and a disgruntled Canadian farmer under American occupation. These individual experiences highlight the brutal realities of trench warfare, naval battles, and aerial combat, alongside the social and political tensions that define this fractured world, such as racial divisions, class struggles, and the devastating impact of war on daily life and the psychological toll it takes on combatants and civilians alike.
