I'm holding out hope that this is true, but I've been burned before when it comes to George R.R. Martin promising a book. Comicbook writes the author teased in a recent journal entry that his sixth book in the A Song Of Ice And Fire series (aka Game of Thrones on television), Winds of Winter, may be released this year. His actual statement makes it sound more like a "maybe" than any confirmation...
“Not done yet, but I've made progress. But not as much as I hoped a year ago, when I thought to be done by now. I think it will be out this year. (But hey, I thought the same thing last year).”
At this point, I think he's just waiting to see how the show finale is received before he finishes the novel. Then again, he really is an obscenely slow writer so maybe he is giving it his best effort. I'm just hoping he completes it already! Any novel readers with me on that?
