Further back and faster

I brain-stormed on Stray Light some yesterday. I'm getting a good feel for the main characters and their problems. I'm developing an interesting time travel mechanism that keeps the story focused on a tight cast, in a well defined setting, which I think is essential for good time travel stories - at least those that aren't fascinated with the physics-of-it-all. Once again I'll be dealing with ghosts and mental illness, dark desire, enemies and families.
