Hello me again. I'm remembering a fic post-season seven. It starts with Xander in America and the others are back in London as he and Spike have split up. He goes back to London where he and some of the others do a version of a spell they did in the Initiative. Tara's soul acts like a barrier to keep Willow seperate from dark magic and Xander hears her voice during the spell.
Any help would be greatly appreciated thanks.
