I'm searching for a specific fic I remember reading (written before CA2).
It was an AU in which Steve fell from the train and Bucky crashed into the Arctic, with a happy ending. Bucky wakes up in the future and is asked to take on the Captain America mantle, which he does, and later they find and rescue Steve, who (I think) keeps the Winter Soldier codename rather than taking it back.
Specific things I remember:
Steve refuses to take part in missions which further the interests of the American government
He's still pretty socialist after the de-brainwashing, and reads Marxist(?) stuff
He donates his army pension to some kind of moscow widows & orphans fund
Does anyone know this fic?
It's definitely not any of the following (though these are also great):
Full of Grace
A Mirror, Dimly
The Ghost and the Machine
