I'm juggling the idea of writing a book set in the Victorian Era, but I want to do it in a very different way, ex. recreating the entire monarchy, and history of Parts of Europe and the US--(It will be set between England and New York). So I need to basically recreate these two cities under different names, and change some major details to make them my own. But I have absolutely no idea on how to go about this, or where to start. Help? It's going to be alternate an world in the sense that the reader will know what the real-life counterpart is, but tweaked to the author's liking, with his (my) own personal 'twang' to it. It's not going to be one of the alernate-dystopian-type worlds, just something different.
