Firefly fic recs, anyone?

Last weekend I went to Windsor to hang with fleshlycherry and jebbypal (whom I got to meet for the first time in person \o/!). Anyway, they discussed the fact that I've nevemr watched all of Firefly, despite the fact that I've watched Serenity, and I own the DVDs. Long story short, we had a good time and they made me watch more Firefly. I'm nearly finished the series, and now I'm kind of jonesing for some good fanfic set post series (but before Serenity).

I'm hoping you guys can help :)

Also, did anyone know Frank Lehne (Azazel from Supernatural) was in Firefly? It always makes me happy when I see him in things). In my mind, every time I see a demon from Supernatural in a future series (actually, just Mark Sheppard and Frank Lehne, who were both in Firefly, too), it makes me think of writing fic where Crowley and Azazel are still alive and doing bad things. Actually, mainly just Crowley, because Mark Sheppard plays really similar characters and is always awesome.
