How Few Remain

From the master of alternate history comes an epic of the Second Civil War. It was an epoch of glory and success, of disaster and despair. Twenty years after the South won the Civil War, America writhed once more in the bloody throes of battle. Furious over the annexation of key Mexican territory, the United States declared total war against the Confederate States of America. And so, in 1883, the fragile peace was shattered.But this was a new kind of war, fought on a lawless frontier where the blue and gray battled not only each other, but the Apache, the outlaw, and even the redcoat.
