Spuffy - Post-Series - Soulmates

[artemisprim.livejournal.com]

Hello. I am looking for a Spuffy story where Buffy has been living off the grid and someone takes her place. Everyone thinks its her except Spike because he's her mate. In the story, not-Buffy sleeps with everyone. Real Buffy ends up crawling in the ceil and Spike knows shes up there because he can smell her.

Thanks in advance for any help finding this story.
