The fragile peace between the United States and the Confederate States of America shatters as a new generation of weaponry is unleashed upon a continent already embroiled in global conflict. The war that began in Europe has spread to North America, igniting a long-simmering hatred between the two nations. While the Confederacy grapples with an internal insurgency, the United States prepares to deploy its industrial might and unleash a devastating armored assault, seeking revenge for past humiliations, but the cost of victory may prove catastrophic.

The premise sets up a complex alternate history narrative, blending elements of World War I with a fractured North American continent. The description suggests a focus on military strategy and the impact of advanced weaponry, characteristic of Turtledove's style. The internal conflict within the Confederacy adds a layer of social and political tension to the overarching war narrative. The potential for a costly victory hints at a somber exploration of the consequences of prolonged conflict and the pursuit of retribution.
