The Unkindness of Ravens

A sci-fi, alternative history on the American Revolution and Civil War
 
In 1859, after the British army conquered the last free colony of Virginia, they move to defeat the remaining Confederate states. After burning much of Nashville to the ground, General McArthur and his 80,000 men meet little resistance as they enter the Confederate capital of Memphis, Tennessee. As General Lee retreats from the combined British, Colonial, and Federal forces, a futuristic time bomb goes off that creates overlapping realities from the 19th through 24th centuries. From the future, Dr. O'Neil Pfister and his nephew Leo9, are genetically and bionically enhanced British soldiers. While their technology is from the 24th century, they face overwhelming odds in the 19th century—not only the Confederate soldiers who pursue them, but hordes of were-men, zombified civilians, and other creatures. Unable to hold Memphis, the British begin a panicked retreat to the east while hoping to reach the safety of British-occupied coastal states. The doctor and his nephew have to take the captured prototype of the time-bomb back to the British scientists—or face an altered landscape and the prospect of world-wide nuclear war.
