Mag7 Fic Finders

Well, I'm a bit shy about being the first person to post a search but someone has to do it!

I'm new to the fandom, thanks to Katherine's Learning to Improvise series. So yeah, I kinda fell in love with Ezra, and with the pairing of Ezra/Vin. What I'm looking for though is your recs for any longer story, the kind you spend all day reading. I'd prefer slash but gen and friendship is good too. What are some of the classics of the fandom?

Thanks for your help!
