People like aliens... and vampires... and zombies... and stories about historical figures with dramatic embellishments.
Of course, if your only aim is to make money, then yes, you will probably turn out fifty shades of something or other and at some point it won't matter if it was once fan-fiction or not. And make money, if you're lucky and that's your thing.
And the first round of edits?
Let me put it this way... we could have saved a lot of time if I didn't have to accept the edit of every single acceptable version of a quotation mark. The fault is mine; whatever program I used to write it had its own version that was deemed unacceptable.
I will try to diligently write my thoughts about the process leading up to my novel's release in the days to come, which will be October 20, 2015, to ensure that I am doing my best to get the word out. Unedited, unabridged, and others such un's. Tell a friend. Tell two, I won't mind.
