Have you ever thought of writing books for a slightly younger audience? I not complaining (I love your Crescent Chronicles series) it's just that I am a fifteen year old girl and it's kinda hard to relate to the characters when they are a few years older and when they seem to be really you know... close.
I do have one YA series that focuses on a 16-year old (The Afterglow Trilogy). In terms of my other works, right now I'm enjoying writing about the college/twenty-something age group. I've found it's an age range I relate to and my voices seems to fit there best.
