Hey, not bad company. I pasted in the first chapter of A Sane Woman, so it got a pretty big sample to work with. Based on the comments I saw, a lot of people get "Dan Brown," which most of them found disappointing.
I did love one comment: "JAMES JOYCE BITCH!"
One person pasted in some Vonnegut and it came back with Kurt Vonnegut, so that's something. And Stephen King is not really an influence on me (mostly because I was writing this way long before I ever read anything of his), but there are definitely similarities.
