As for the demographic of who would love it as it is? yep, you have it on the nail. 40 something women (and men for that matter) who love fantasy. It was never specifically written for the MG age group, I was just told that my writing style (and the lack of sex and violence) would make it more suitable for that age group.
Hmm if you're targeting a demographic for this reason alone, it's probably more of a hindrance than a benefit.
I tend to hover in the background and find creative ways to thin people's casts. Chapter one's are easy... have it so your group isn't assembled yet. I got my group together in chapter 14. I think Amy took an entire book to get hers assembled.
