Very, very good! It's quite a curiosity, the tale you've spun. I'm not sure what else there is to say, it was so well-written that I can't critique it.
Sincerely,
A good idea, and a nice writing. It's nice to go through Carlisle's thoughts and see what he really thinks. And I like the ending too. Kind of a foreboding for people who haven't read the books yet.
