There was a thread about this in the WDW forum a few months ago. It is closed now though, so sending you there won't help much!! A funny connection though is that I just gave this book to SimplyMad tonight...so it was weird to see it here!
I'll share what I wrote about the book back in January --
I'm a mom and I got it for my DD but it is still a bit above her reading level, so I read it. And since then I have recommended it a lot! It's a great read. There are some holes in the plot lines here and there that aren't explained very well, but they are easily overlooked by the rest of the story being so well written.
I've really been turned on to reading Ridley Pearson's young adult stuff since he started co-writing with Dave Barry on the Peter Pan books (pre-quels to the story we all know and love). If you haven't read those and you like Peter Pan, I highly recommend them - except for the part about Tinker Bell. That part was weird to me. She has always been a fairy born from the first laugh of a child. Pearson/Barry take a different approach to her creation that still bugs me. Great book otherwise though.
Funny thing - I love to read, but since having my son (he's nearly 3) I find less time to read a good long book. So, I've started ordering books from scholastic when my daughter brings home the catalog. She likes fantasy books so I stay mostly within that genre and order stuff that she'll read in a year or so - but in the meantime, I get to read them. That's how I ended up reading Corneila Funke (Dragon Rider) and she led me to lots of other great books too.
