Spike is an angel

Hi everyone,
So I'm looking for a fic that is post season 7 and maybe post NFA? The scooby gang is together somewhere and Buffy is missing Spike. Willow is doing a spell for Giles and by accident returns Spike from some dimension. He starts doing strange things like turning his clothes white and then throwing up blood. Later they find out that he's actually an angel and he feeds on the bad slayers' blood...including Kennedy.
Help Please!

This is the only one I know:

Daemons Luminati by Kalima

Summary: Can a vampire be dragged, kicking and screaming into the light? We'll see. Spike's a complicated guy, isn't he? Story Notes: Season 6 through, oh, I don't know, let's say after she wore the lilac blouse of breaking up and before she wore the gray robe of victimization.

I'm pretty sure you're thinking of "When Tables Turn" by C Roxane.

There is one where Spike is feeding from slayers - *rereads*
Indeed, Willow did a spell to call for an angel to open a metal box. So it could be the story you're looking for.
I'm sad that there never was a sequel like she said.
It was at The Sandlot, sadly gone but is still at SA:

When Tables Turn by C.Roxane
