For our Spike/Xander slash fans, I wanted to pass along this recommendation in case, somehow, this writer has escaped your attention. I absolutely LOVE 'wordsmith slash'. Especially these two stories, which, like Spanderverse takes place during S5. Instead of writing from the beginning of the season, these specifically focus on the aftermath of Buffy's sacrifice in "The Gift" and the gang trying to pull themselves together.
I often return and re-read Reconstruction and Restoration when I can't find anything else new to read because it is that good. Thoughtful, in character, heartbreaking and sweet. And there's lots of heat between Xan and Spike, of course.
