Apparently I write like Steven King:
At least for the novel I've been working on. Which is, I suspect, a large part of the problem I'm having completing it since I don't actually like Steven King's writing style.
The one fanfic I've written has been in the Harry Potter fandom. For that story I write like J.K. Rowling, which is actually kind of nice, even though I suspect it's recognizing names and slanting things from that.
