Dark Lord of Derkholm - Diana Wynne Jones

I totally enjoyed this book. It's young adult fantasy, but it's also a satire of fantasy - the inhabitants of a magical world have been forced to enact stereotypical fantasy roles and activities in order to provide entertainment for tourists from a world like ours. The characters' responses to these roles are pretty funny. There's a lot of heart and humanity in the story - emotionally, it's actually pretty deep. It was so fun to read, and gave me plenty of real things to think about beyond, you know, the elves, griffins, and flying horses and whatnot.
