In the annals of Spuffy Fanfiction history I think
Nan Dibble can be credited as having written the book(s) - I punned

- on season seven re-writes. Starting at Showtime with
Old Blood. It's very Spike and Dawn centric and Nan loves those saintly aspects of Spike. It's worth reading to see where so much "fanon" comes from.

TheDeadlyHook has started a complete rewrite of S7 on her journal but it's barely begun. You can never tell where that will go, but Spuffy is an odds on bet. She's a fine writer who loves all the characters.
