It's interesting to me that some YA authors have said they don't write specifically for a YA audience and yet that's where most of their books end up*. I think theirs are also the books I tend to re-read, or whose books "grow up" with me -- like I find different things in them as my life experience changes.

*I don't think this is a bad thing, necessarily, unless 1) they're bashing the YA genre or 2) being in YA is limiting their readerships because adults won't read kids' books. *eye-roll*
