I have to say, this is one of the best timelines I have ever read. It rivals even those of Harry Turtledove, at least the Confederate one. (The Alien Intervention in World War II series was.....weird). And the fact you are doing this with only history as a base, makes it even more incredible. You should polish your writings, and begin releasing it as a series.
I've never liked Turtledove.
Turtledove writes crap.
Turtledove is a fairly good short story writer who because of the realities of what it pays for an author to write these days, writes "novels" that are little more than a threaded together assemblage of short stories with a common setting since that's what pays.
I like Turtledove because, in the case of the Confederacy series, takes a rather small change and produces a whole series. That, and he shows how all of society is affected by the situations that occur within his universe. The writing itself I do not care for. If it was up to me, I would have Stephen King writing those stories, or at least improving upon the sentances. At the same time, it would be a different read, and the books could be completely different.
