I actually really suck at naming books, so lots of years ago, readers were sending in their ideas for titles, and what we realized is that they were smarter than us. So we thought, Hey, go for it. So now we have a contest every year.
I'm always trying to do stuff I haven't done before or challenge myself so I'm not resting on my laurels all of the time because if I just found my little niche and never left it, I'd be pretty boring, I think.
