What's In A Title?

My novels have mathematical titles - I even call them "mathemafiction" when I'm feeling whimsical. The titles have the advantage that there aren't many other novels sharing them, but that doesn't help people find theem on Amazon. You type one title, and Amazon helpfully guesses you really meant another. So my novel (Divide by Zero - the only one published yet) languishes behind Continental Divides and the Zeros of Dangerous Ideas - and then only if you specify you're looking for a book.

Divide...
