It takes courage to write an honest, truthful tale. Your work has always seemed to possess this quality. You carve your art from your own flesh, offering it to any who would partake of it. This is beyond brave.
It also takes courage to forge a new path for yourself. The YA market is your new chosen path. I'm sure you will find new stories to tell and some new ways to tell them. You're work is uniquely you and I celebrate that fact whenever I read it.
