This is an old story, probably about 3-4 years old maybe older. The subject line was really vague and I am so sorry for that. But what I do remember is that Willow does the spell to bring Buffy back, I believe TPB interfere so that Buffy isn't as emotionally damaged as she would be if following canon, and Buffy distances herself from Willow. I don't remember if it was a full ensemble cast (for the life of me I don't remember Giles, Anya, Xander featuring in it all that much, but I could be wrong).
Because of the resurrection there's changes to (I believe) Buffy, Dawn and Tara. And it's said that while Dawn is made of Buffy- and Buffy as well as Spike are her protectors Tara is her teacher (and a little bit like her soulmate). Willow is in denial over what she has done and tries to "fix" things, which gets her powers stripped from her by Dawn (as the Key) or Tara. And she kinda goes off the deep end, blames Buffy and Dawn for Tara leaving, and tries to find way of getting her power back, or hurting Dawn and starts stalking them (hiding in bushes at the house, listening in on convos, following them, etc.)
Although it doesn't sound Spuffyish, it really is cause Spike is there helping, calming, loving Buffy, etc. But I figure that describes 95% of the Spuffy stories out there so I added what made this story unique in my book. Also there are hints of Tara/Dawn slash. Nothing graphic, but I figured I would put that in there cause there aren't many Spuffy stories i have read with that pairing.
