I think I have a new favorite artist. These are all done by a guy named Trillian who posts on http://www.reddit.com/r/asoiaf/
Here is what we know. According to George back in 2010, he had four chapters already written.
But it’s good news for DANCE, since I’m now two chapters (the ones I hadn’t finished) closer to completion. And hey, it’s even good news for WINDS OF WINTER, since I now have four chapters done for that one (an Arya, a Sansa, and two Ariannes).
And we also know that there is a Theon sample chapter, from George’s other post. That brings is to five chapters.
And George has also recently posted that a new sample chapter will be included with the paperback version of A Dance with Dragons.
How many others could have been written in the past 2 years? That we are not sure about.
