thelilyqueen.livejournal.comI read both of these some time ago, so I'm not going to be shocked if they aren't found.
Fic 1: WIP when I read it. Had a title derived form literature or a poem, and centered on Peggy Carter finding Natasha as a little girl when the SSR raids a facility after WWII ends. They take to each other, and it looks like Peggy might eventually wind up adopting her. Gen.
Fic 2: Completed, I think. Bucky has been recovering from being the Soldier and seems to be doing well. Not that he hasn't been generous when he can before, but Steve has noticed it's bloomed into (despite the Russian associations) a sort of individual socialism. He doesn't expect it of anyone else but 'always' leaves a substantial tip, donates pretty much any money he gets beyond his needs to charities and socialist-leaning groups, etc. Might have been gen, or Steve/Bucky.
Hope one or both sound familiar to someone!
