Very well done! I loved the concept of revealing one's alternate future ala A Christmas Carol ;). Methinks the bond between Tom and Sara could have been explored a bit more indepth but meh, I think you did a good job anyway. I enjoyed reading this a lot :)

That was an interesting story. It's a one-shot right?

Um... the "dirty sex" part kinda got me as well as Cassiel's change as a whole after she took off her cloak. It was unexpected. Maybe you should go back and check for typos. As a whole, it was very interesting. Very creative. Good job.
