An all-new collection of stories edited by the “master of alternate history” (Publishers Weekly)—featuring some of the most popular authors in the genre— timed to coincide with the 150th anniversary of the American Civil War. It was the bloodiest period in American history. Millions of men battled for almost four years over states’ rights and slavery, and when the smoke had cleared, 620,000 lay dead on the battlefields throughout the eastern United States, with another 400,000 wounded. But when the echo of the last rifle shot had faded away, America was whole again at the end of the Civil War. Now, almost 150 years later, this brother-against-brother conflict still holds a powerful fascination for our own nation as well as people around the world. But what if things had happened differently? What if General Robert E. Lee’s invasion of the north had culminated in his capture of Washington D.C.' What if Great Britain or France had come to the Confederacy’s aid? What if Lee or Grant had been killed in battle during one of the campaigns? From the various campaigns on the fields of battle to the different allies and enemies that may have joined the fight, the clash of the Blue and the Gray will be re-imagined, re-interpreted, and refought by some of today’s best alternate history writers including brand-new stories by Orson Scott Card, S.M. Stirling, William Forstschen, Eric Flint, and Mike Resnick.
