Strongest possible rec for
perspi's latest: A World Called Catastrophe. Sheppard's life changes dramatically. It's a story I've never seen in SGA before, told beautifully. Gen, with strong team friendship (but you can read McShep or Sheppard/Dex undertones into it if you're so inclined).
If you like Stargate Atlantis at all, read it!
