Okay, so I don't do this nearly as often as I should. But, in all honesty, I don't read fanfic nearly as often as I should. Call me picky, elitist, whatever.
Anyway.
If you haven't already, go read
"The Memory Remains" by
azewewish. It's Supernatural gen fic, dark, and Dean-centric with Sam and John thrown in. It's hands down on of the 3 best things she's ever written. She makes the whole thing work in a way a lesser author couldn't have, and she captures WHO Dean is and what's important to him and his absolute, unswerving faith in his family.
Trust me, this is a fic you shouldn't let yourself miss. :)
