JKD, I've had over thirty books published -- mostly children's and preteen, although some of them have been adult books as well. Over half of these were part of one or another series, and about a dozen were actually translations from Hebrew to English.
I'm not sure if I'm what you're looking for, though, because I was a "profic" writer long before I started writing fanfic. I'm
much more interested in authors who honed their skills on LnC, got lots of lovely FDK to encourage them to keep going, and then took the bold step towards going profic. Kudos to Erin and Emily and Debra, and long may you publish!
Hazel, who thinks
most of our fanfic writers are better than much of the profic out there
