Belatedly remember to post a link to one of my favourite fanfics - it's an AU version of Firefly set in the Buffy universe, in which Mal is the sheriff and Inara the mayor of a small town called Serenity, Nevada, which suddenly aquires some supernatural problems. All of the other main Firefly characters are in there too. Considering how strange the idea is it works surprisingly well.
