In this story Buffy gets horribly burned across her back and has trouble adjusting. She later starts sleeping with Spike and things don't go well. This fic has been eluding me for a while. Hopefully someone can help. Thanks.

I have a copy, if you PM me I can send it to you.

Scars by JamesMFan

Summary: Set during Season 4, no Riley and Spike doesn't have a chip. Buffy is still reeling from the events of the past year, where she was scarred both physically and mentally. Now, to make matters worse Spike's back in town.

This appears to still be available on this site too.

I was looking for this story - I had been reading it and lost the title - thanks for the info - what a shame that the other story was never completed.
