So, I've had a cup of tea and a moment to calm down, and have (mostly) silienced my internal screaming. It's time to review everything we know about book five and update our theories.

There may be minor SPOILERS in this post, so if you don't want to know anything about the book other than the title and cover before you read it, please do not click.


I will try to add new information to this post as it becames available. If you see anything missing, please post it in the comments.
