When I was 6 or 7 (So we're talking 1990/91 here), my Mom got a book out of the library for me. I believe it may have skewed more young-adult than kids.
Here's what I remember:
The general premise was that the book seemed to take place in a sort of Medieval setting. But as the pages wore on there were references to skyscrapers and modern items, indicating that it was in the not-so-far future. There were some references to, I think, gargoyles that had either torn the buildings down or policed the skies to make sure they didn't go back up.
The main characters were children, I think they were cared for by a Grandfather.
I believe they were at a carnival at some point, almost certainly at a freakshow.
The author was a woman (I think.) and I think the book garnered some number of awards so it can't be too obscure.
I've been trying to track it down ever since. I never finished it- Hell, I don't even think I got that far in- but it's always been knocking around my memory. Help!
I've posted this all over the internet, no one can find it. Any chance you guys recognize it?
