Chaos says not to talk about that, in the other thread this was posted in.
Unfortunately, I really need to shut this topic down. We just have a policy of no spoilers from unpublished works. I would not want to spoil anyone reading the book. However, he did confirm a while ago that the Letter's recipient was on Yolen, so I'd say this isn't new knowledge Thanks for the information at the signing though! Feel free, if there was more info from the signing, to make a topic in Signings about it. I just really don't want anyone talking about unpublished stuff. Sorry guys for closing it...
