OC based ("elsewhere") fic, human girl betrothed to a vulcan

[jomy-rewound.livejournal.com]

This fic was pretty old, I believe, I think I might have read it on an independent archive (old fashioned webpage type), which is probably why I'm having trouble finding it.

Basic rundown: the daughter of human archeologist on vulcan gets betrothed to a vulcan boy as a child, vulcan style. I think the boy's father was the girl's father's coworker.
Way later in the story things go awry; I remember that the girl was raped and ended up really insecure about the betrothal. I'm fuzzy on the details, but I think her mother wasn't a shining example for humanity? Oh, and the last bit had the obligatory Pon Farr suspense.

I remember early in the story that the archeologists had found some glass objects (bottles?) and a comment about vulcans making glass very early in their history because they didn't have clay.

There was an eventual happy ending.

It's really bugging me right now, so any help would be appreciated.

FOUND: It was actually on AO3, though the author is old. I had also been reading stuff at House of Tucker at the time, which is probably why I thought I'd read it on an old fashioned archive.
