I'm pretty sure you're talking about Coyo's fanfic East by West: http://uss-spambot.dreamwidth.org/11102.html here. But you'll have to drop her a line here http://uss-spambot.dreamwidth.org/ to be added since all entries are f-locked to read it. If even if the first entry has been f-locked, you'll have to pm her about it. She did have a website set up, but it's been down for years now. If you have the old url, you might be able to wayback machine it.
