Most traditional publishers refuse to publish more than one or two books per author in a given genre, out of a perception that it will hurt sales because the author's fans will only spend so much money on books from a single person per year. This is why so many authors have secondary pen names or force themselves to cross over into compatible genres. (eg. fantasy and sci-fi) And of course, it can take an entire year to go from draft to published novel... Traditional publishing is a grossly inefficient industry.
