General search: Gabriel/Sam or Gabriel/Dean or Sam/Castiel AUs

[synn.livejournal.com]

Hi all,

I'm hoping for some general recs for Gabriel/Sam, Gabriel/Dean or Sam/Castiel stories where they are:
 - AU, Not established relationship, not PWP.
- The given pairing above is the *main* pairing of the story. There are a lot of great gabriel/sam on AO3 (and i've read a lot of them), but they always seem to be primarily dean/cas with a side of sam/gabriel, and as much as I love destiel, i'm looking for a different focus at the moment.

Happy ending is a must for me, but i'm really okay with any amount of angst etc before that, all kinks and genres.
Many thanks in advance!
