OK so the main premise is that Jenny didn't die. Instigation explains this and Goodbye deals with the aftermath. Jenny is in a coma till towards the end of season 4... I know how she comes back but I've not decided exactly when... but I will do soon, honest.)
Much of the recent stories have concerned the child she and Giles have, Cassidy. She is the first born... she is human but she's grown up around the weirdness rather than having weirdness thrust upon her.
For reasons that will become apparent (when I actually get around to writing about them), she ends up in London. She wasn't meant to stay very long but stuff happened and she sort of had to stay. And she couldn't stay on her own... (see Bolero, and Stolkeren.)
Then she fell in love... (see Fight...) and started to change the world. This obviously pisses some people off... (Dream)
After Dream Cass and Spike decide they have to move. Plans kind of deals with part of this, though it was written as a gift.
Then there is the new series which I'm writing at the moment. This is set 5 years after Cassidy's arrival in London. It is untitled at the moment but the first part can be found here...
Anyways all your favourite characters are around here somewhere... I just added my own to fight a boute of writers block and fell in love with her.

(I'll update this explaination as and when I get more stories up...)
