It's a tie between Murder by Mistake and Potent as Blood! I think it's Murder By Mistake, though, because I'd never read a fanfiction of that length all the way through before, but it was SO GOOD I could NOT put it down! It was also the first fanfic I read even though it had no smut. The premise drew me in and the story and prose held me riveted. (ps: please write moorreeeeeeeeeeee ^___^)
Anon, I am so thrilled to hear that the fic kept you riveted even without smut—as an author who doesn’t smut, it can feel like you have to work a little harder to hold attention (not as much in this fandom, though—I like to think we’re all over the spectrum)! I literally threw my fists up in the air and shouted “victory!” when I read this message.
As far as writing more goes, I have one little story to write for my sister who has been waiting very patiently AND THEN I have eleven blank notebooks, eight reference books, and a mountain of plot to get me started on MBM III! I can’t say when it will come, but I promise it will.
