AU recs

Stargate: Atlantis

Push and its sequel Pull, by jane_elliot. Slash Rodney McKay/John Sheppard. (ca. 39,000 words and 27,000 words)
It's somewhat like a Harlequin romance story. Rodney, who works at the SGC, has an accident with Sheppard, who lives on the streets as result from his severe PTSD and dishonorable discharge, which circumstances are slowly revealed through the story. Then friendship and romance follow with a fair but not overwhelming amount of angst.

Unidentified, by the_drifter. Slash Rodney McKay/John Sheppard. (ca. 30,000 words)
Everybody recced this already, but it a really good present-day (no Stargate) amnesia AU, in which Rodney looses his memory suddenly without explanation, and we see him (re-)discovering and to some extent redefining himself and his relationships to friends and family through Sheppard's POV.

Harry Potter

The If Sieve, by Cathy (crawfords_lover). Slash, Harry/Draco. (ca. 36,000 words)
Draco goes through potential alternative universes with a pensieve-like device, exploring what would have happened if he (or Harry) made different decisions. It's a cool magical device and the scenarios are HP fandom staples, but handled in an original way, often with not quite the expected outcome.

X-Men Movieverse

Forgotten, by cyndrarae. Slash, Scott/Logan. (ca. 2,450 words)
In this AU Scott survives X3 but has amnesia, and Logan eventually finds him. Also it is hookerfic, so you get two fannish tropes in one, which in this case is definitely a good thing, since they go great together with Scott angst.

Crossover Recs

Untitled, by siriaeve. Gen, Aiden Ford, Ronon Dex, Rodney McKay, John Sheppard, and the Endless. (ca. 750 words)
Sandman/Stargate: SG-1/Stargate: Atlantis
It's a "Five Things" type story in which SGA and SG-1 characters meet the Endless, and while each vignette is short, they are also gorgeous.
