coalitiongirlHi,
Thanks for your response.
I began scanning the first few chapters to check. I don't think this is the one though. Sang et Ivoire has Spike running into Giles at a cafe in London and reluctant to work with Spike. The one I am trying to remember has Spike literally arriving at Giles' front door at his home, I think in Bath, and Giles can tell right away that Spike's had a major change and invites him in to stay. Also, I notice in the warnings of Sang et Ivoire there is Vampire!Buffy, but in the story I'm searching for I don't recall such an event.
But I'm still going to read Holly's fiction as it does sound entertaining and I've enjoyed other stories by her. So thanks again.
