GDG- Alternate history

[Dave]

I've been fascinated by the civil war and particulary gettysburg since I was old enough to read. With my knowledge of the war, I've begun to write an alternate history novel in which the twist begins at Gettysburg. I have about 120 pages thus far and plan on finishing it within the next few months maybe the next year, but was wandering if that sort of thing was still popular. I know it came and went when Newt Gingrich and William Forstchen put their best seller out but I'm not sure about the present time. If anyone here is interested or knows whether the topic will still sell please let me know. Thanks
