My writer's group will all be on board, and so I will as well, with the caveat that I don't (generally) write fiction.
So I'm kicking it out to you. We'll make it a contest. You suggest in the comments what you want me to write about next. I'll pick a winner and give myself thirty days to write the first draft of that book. If it falls into a category that my regular publisher will be interested in and it holds up... the person who suggested the subject and title will get a signed copy. If it doesn't fit that category, I'll do it as an e-book and e-mail a copy to the winner.
So, since there's a chance that multiple people might want the same subject, you have to suggest a subject, a title (especially since I suck at titles) and leave enough information in the post that I can contact you (or at least give you a shout out) so I know where to send the results.
