Instead of starting off my query letter by introducing my book and giving a summary, would it be ill-advised to instead start off by mentioning my target audience and talking briefly about the market? Then after stating my case about the market I would get right into the introduction and summary of my book. I'm writing my first draft for my query and I feel like my biggest selling point is the market -- there just really aren't a whole lot of books out there about this subject matter for this age range (7-10). So I feel like that lack of competition is a point I want to hammer home. I know its a good idea to make your case for marketability in a query and everything I've read and researched about queries suggests putting this a little further down in the letter. What do you think? Yay or nay?
