Spuffy with little girl named Holly

I'm looking for a fic taking place in a secluded cabin somewhere in the mountains. It's a LONG fic with lots of play in the snow and some Christmas time emotions. I'm not sure if Joyce was originally with them, but had to go back... At some point a little girl (4-5 years old) joines them and Spuffy take care of her. Later in the story assassins try to kill the girl/Spuffy, but in the end all is well.
Does somebody remember anything like this story? A little help or some guesses would be great.

Thanks
Carrie

Promise of Frost by Eurydice is the fic your'e looking for; sorry I can't post a link for you.

Yes that's it! I found it.

Thank you so much. I've been looking for this since before Christmas.

There's a sequel titled Decking the Summers' Hall (I think) it's short but kinda sweet scene with Holly and Spike.

When a snowstorm strands Buffy and Spike, they are forced to turn to each other for strength, especially when a missing Giles, mysterious visitors, and way too much magic threatens to turn it into a not so very merry Christmas. Set mid-S4.

This takes place in my Promise of Frost 'verse, one year later. That makes this an AU mid-season 5 where Giles has custody of Holly, Spike is her nanny, and all three of them are living with Joyce, while Buffy is going strong in college.
