Well, I have read the new George R.R.Martin, which is of course one half of the new book, since it only deals with half of the characters' story lines, and we get e.g. John Snow, Tyrion and Daenarys in the next part.
No spoilers, because that would be unethical, except to say that this is a book in which no-one is safe and unpleasant surprises are a way of life and death.
I am interviewing George later in the month. Any questions people want me to ask?
