I think it would be so cool to see your name on a real book too. Ask Mare, she knows that feeling! Another writer from AC, Kelly Oram (honey), has also gone on to be quite the prolific published author, and at least one of her books was originally posted here as a fanfic.
I have thought about trying to turn one of my fanfics into an original novel and even attempted it once, but it is harder than it sounds! A few years ago, I had the idea to rewrite my story Broken as a YA novel; I planned out all the changes I would make to de-Backstreet-ize it and even started writing it (the first few chapters are on AC), but I could never get very far on it. I'm not sure why. I thought it would be so easy because the original story was a breeze to write; I was obsessed with it and never had writer's block. Re-writing has always been really tough for me, though; I lose interest in it quickly. I think it would be easier to write an AU or something that could be revised instead of totally rewritten. I attempted to do that with a different story, Secrets of the Heart, but I finished that one four years ago and haven't pursued trying to get it published. Maybe someday... It worked for the Fifty Shades writer, so why not us?
