Epic Length McKay/Sheppard (Recs)

[scarletfbl.livejournal.com]

I'm requesting, not only for myself, but for my friend who's become curious about the SGA fandom. I'm looking for the most epic length, really well written McKay/Sheppard fics. Your favorite recs would be awesome. Any warning (mpreg, non-con, etc), any genre (au, romance, etc.), anything goes. We pretty much read anything. (^_-)

Please and thank you!
