Print-on-demand publisher lulu.com has come up with an interesting Titlescorer to tell you if your title will get your novel onto the bestseller list. They hired a team of statisticians to analyze the titles of the past fifty years of the New York Times hardcover fiction bestseller list, with a control group of bestselling authors' less successful books, in order to create a program to detect what elements of a title show up as bestsellers the most. While I have a few problems with the methodology (I'll let you figure those out for yourself) it's lots of fun.
I haven't had a novel published yet, but I've written three and I've started a fourth. My first, Hard Winter, has a 69% chance of being a bestseller! My second, Roots Run Deep, came in at only 22.9%, while my third, A Fine Likeness, got a measly 10.2%. Strange, because that's my best work yet! My work in progress, with the working title Unity, has a 59.3% chance of being a bestseller. I don't really like that title, but maybe I should stick with it.
