Buffy gets kicked out and turned.

Okay so this fic picks up after the big betrayal in S7 where they kick Buffy out of the house. I can't remember if it was a long fic or short fic, but she falls asleep in an abandoned house and she wakes up and is SURROUNDED by vamps. She loses, they turn her, and she kills them or something. Spike finds her by tracking her blood, and I think she eventually gets someone to get her a bag full of clothing and stuff from her house... and that's where I can't remember.... if you can help me, you are amazing.

I can't remember if she is evil. I don't think she's evil but I don't think she has a soul.

Soul Inside was the first story that came to mind, but it doesn't exactly match your description.

Summary: What if, in 'Touched' when Spike and Buffy were on the bed together, Buffy didn't go to sleep. One small act can change the outcome of S7....

There's also a sequel that's unfinished...

Know the Price by velvet cat

Summary: The sequel to 'Soul Inside', picks up where that left off. If you haven't read the previous one, then this one won't make sense!! Go on, read it; you know you want to...

That's not it but thanks for the read.

Actually that's one of my unfinished works.

Sorry on my tablet so not sure how to do the link!

I lost a whole chapter of that story and two of my others when my computer crashed. I havent written much since then but keep hoping to finish them.

Summary: This story starts at the end of Dirty Girls and becomes Au after that although certain points do stay within canon of the show. Buffy has been sent out into the night turned away by her friends into a world none of them was prepared for. How will it affect her and how will it influence their battle with the First?

Asked Mhustler and she confirmed this is the one she was looking for and said 'thank you! you rule!'
