George R.R. Martin has posted a new entry to his Not a Blog, titled “Back in Westeros”, which discusses the self-imposed isolation he’s been in for much of the year. In a mountain cabin somewhere in the mountains of New Mexico, George has been making progress on The Winds of Winter, and reflects on how the periods in his career where he’s been the most isolated have also been among his most productive.
Towards the end, he gets a little more specific about what he has been working on lately in terms of point of view characters, and one of the one he names is a bit of new information as their presence as a POV had not been confirmed until now.
(No, this is not actually his cabin!)
