Patricia C. Wrede Enchanted Forest Chronicles

I hope this is the place to put this question--does anyone know any books similar in tone to Wrede's The Enchanted Forest Chronicles (Dealing with Dragons, Talking to Dragons, etc)? My friend can't think of any like hers--I'm looking for the way the myths are redone, like how Cimorene volunteers to be a dragon's princess even though it's "just not done", etc. Thanks

Usually it just gives me fantasy books in general, but it's been awhile since I checked. I'll definitely look for the Unicorn Creed though, thanks
