So I have been thinking about writing a short (50-75k word) novel inspired by Fifty Shades. I consider myself literary, and most of the other books I have written have been intellectual works (non-fiction). But I simply can't ignore the commercial potential of a book like Fifty Shades. You don't even have to sell 20 million copies to make a small fortune and be set up for life. What do people think? Is this the new gold rush? Is there still room to make money as an author this way? Is it cynical to see my authorship as a commercial endeavour?
