Recs, please!

 Since it's time for some summer reading, I'm hoping to find some good AU dramione fics (preferably completed, but I'll take what I can get). By AU, I mean not only EWE or not compliant with the last book---are there any good fics where they switch houses, or are in an insane asylum, etc....You know, considerably different universes, where the setting is strange and new?

Thanks!
