This sounds like an old and brilliant WIP by Mary, the Journeys series.
I absolutely love this fic and it is very long with a lot of amazing detail about the characters and their feelings-- even if the amazing hints and foreshadowing don't find a resolution because it is a WIP and will likely always remain unfinished. the look into Spike and Dawn's friendship, and their views of the world, are fantastic and real.
On All About Spike, the first and second stories are up in their entirety-- Journeys and Journeys Part Two: Awakenings. It starts off a bit slowly, but what you mentioned about Buffy calling Giles Rupert and being a little off with time because her experience in Heaven seemed to last for centuries sounds like Awakenings. The author did post a short rough draft and a glimpse into where the third part of the series would have started, Revelations, but that was a long time ago. |
