What I Learned:I don't write YA. Really - I did learn that. I also learned a lot of tidbits that can be applied to all writing. Like that the reader should care about the characters and that the hero has to have a problem.
Also - girls read boy books but boys don't read girl books. So if you write a boy book you can hit the whole market. Actually - I realized I should have known that already since I read many a boy books growing up - and still do.
