Muse Gone Missing

Calling all fiction writers. Here's a question for you. What do you write about? I'd really like to hear from any of you out there, and find out. For years, I always had some kind of running script in my mind, a proverbial movie in my mind. Lately that seems to have gone missing. I still write, but I can't find my fiction loving writing ability anymore. Maybe the question should really be, where do you find the muse when she's gone missing?
