Hi Everyone-
I've been peeping in on the Davidson discussion boards for years now while raising my now 10-year-old, but this is the first time I felt compelled to register and post.
Nautigal, I agree with the other posters, shorter is less intimidating for many younger ones. My daughter cruised through the MT series at 5 partly because of the sense of accomplishment she got from "finishing a book." (And flower -you made me laugh about small books being easier for sneaky-reading. My daughter still gets in trouble for reading at school. Gosh, that sounds odd, but it's true.)
But you're the writer, so it's up to you.
As far as self-publishing goes, I just listed a book on Kindle -written for the same reasons as you - just to provide fun reading for young advanced readers. But now that it's up there, I have realized that while a lot of teens buy ebooks, and moms load up picture ebooks for the younger crowd, the 8-12 crowd still relies primarily on librarians to help them find new books. (Or just going to the library and cruising the shelves.) So at least for the near-future, it might be better to aim for the traditional publishing route. That's what I plan to do now.
