I love a good AU, so here are two fics that you may have missed!

Naked Pantomime in the Dark is a high school theatre AU. Yes, I know high school AUs can be terrible, but this one is brilliant. Everyone's still in character, the dialogue is great and Clint and Natasha are adorable.

The Lady and Her Hawk is a new fic that could do with more love, especially since reviewing seems to have died out on fanfiction.net. It's a medieval AU that feels well researched, at least to my limited knowledge. Clint and Natasha are in character (and hot) and Tony and Pepper have fun side roles. The dialogue can be a little verbose at times, but that might also just be the setting. Recommended reading if well written, plotty AUs are your thing!
