I've just posted a story called Messing With the Mouse on the Buffyverse crossover site Twisting the Hellmouth - http://tthf.me/7lZc

Like the last one, I won't be posting it here because it's set in a hugely complicated multiple crossover setting created by Diane Castle which must be getting on towards a couple of million words by more than a dozen authors - the bits you will need to read for it to make any sense, at a minumum, are the first and third stories of this series: A Brane of Extraordinary Women - together they're about 1.4 million words! I think it's a fair assumption that most people who read this will already be familiar with this setting from having read these stories over several years, so I'm not going to try to explain it here.

In case I forgot to say so my previous story in this world, Bad Medicine, is complete - http://tthf.me/klBc
