Rec me the good crack

[jic]

I need Atlantis fic -- long, plot-ful, slashy, McKay/Sheppard fic with good characterizations and better romance than "A suddenly realized B was hella hot"

And by long I mean ~10K words or more

Clearly I've been spoiled by Shalott's fic:
A Beautiful Lifetime Event
Transcendental
Proof by Contradiction
