The Guns of the South: A Novel of the Civil War

A "what if" story imagines what might happen if a band of white supremacists traveled back through time to alter the outcome of the Civil War.
Northern Virginia is ragged and ill-equipped. The battle of Gettysburg has broken the back of the Confederacy and decimated its manpower.
Then Andries Rhoodie, a strange man with an unplaceable accent, approaches Lee with an extraordinary offer. Rhoodie demonstrates an amazing rifle; its rate of fire is incredible, its lethal efficiency breathtaking--and Rhoodie guarantees unlimited quantities to the Confederates.
The name of the weapon is the AK-47.
"As a Civil War historian, I literally could not put The Guns of the South down. It is absolutely unique--without question the most fascinating Civil War novel I have ever read. Harry Turtledove knows his Civil War. And best of all, The Guns of the South is not simply great entertainment; it is also a serious and successful effort to come to grips with the central issues of the war. It is must reading for every Civil War student."
