It seems no one's more upset about George R.R. Martin's inability to finish the next Game of Thrones book than George R.R. Martin himself.
While promoting a new book that he actually has completed, Fire and Blood, Martin told Entertainment Weeklythat getting the history of House Targaryen done was "emotionally a big lift" for him. After all, he said, he's "mad" about the fact that he's still toiling away on The Winds of Winter.
"I've had dark nights of the soul where I've pounded my head against the keyboard and said, 'God, will I ever finish this?'" he said. "The show is going further and further forward and I’m falling further and further behind. What the hell is happening here? I've got to do this.'"
After initially starting as an adaptation of published material, the past two seasons of Game of Thrones have covered events beyond Martin's existing books, the last of which came out in 2011. Considering Martin plans for his series to consist of at least two more books, the ship has sailed on him finishing it before HBO, meaning he won't be the one to bring the ending he has been planning for decades to life.
