Speaking at the Edinburgh International Book Festival, the American author said that he had thousands of pages of unused material that did not make it into the final version.
And while he wouldn’t publish most of it because they are earlier drafts of chapters, he did say that there was one segment that he might consider turning into a separate piece.
"There are discarded chapters and paragraphs and everything in-between. Because I follow the characters and they sometimes lead me down dead ends. So, at the end of the sequence, I will probably have tens of thousands of words or even hundreds of thousands of words of unused material," Martin told The Guardian.
“There's at least one deleted chapter from book five – which left me in the wrong place – which I have been tempted to publish as a sort of short story”.
