Buffy and Spike are forced to marry to form a treaty between the humans and the aliens.

I was reading a fantasy AU story a while back. Buffy is a sort of space cadet and lives on a space station with some of the scoobies. Spike is apart of some sort of alien race that lives on a planet. I think Dawn was his sister. Buffy and Spike are forced to marry to form a treaty between the humans and the aliens. It wasn't completed when I was reading it. I've tried looking so if anyone remembers this fic help please.

Truce by Eternal Red. Here at SR.

I think you are looking for "The Truce" by Eternal_Red.

It is on this site.

Yup that's it thanks so much for the speedy response!

Oh, how I wish this story would be updated again. It is so excellent, one of my very favorites.

Sorry SpikeBaby18 but I will have to ban you for breaking one of our rules. I will however, fix the subject line and move this since it has been found.
