New Genre for Pot Thief?

The Albuquerque Journal ran an article on December 18th about books published in 2009 related to New Mexico that they recommend. One sentence said, "The best-selling adult book in this little shop is the paperback The Pot Thief Who Studied Pythagoras (Oak Tree Press, $15) by J. Michael Orenduff. It's a lowkey mystery set in Albuquerque's Old Town." Maybe having it described as an "adult book" will help me raech a new audience? The explanation is that the previous paragraph was talking about books for children. The article was picked up by the website AllBusiness, which generated a googlr alert for me, so that's how I found about the the newspaper piece.
