George R.R. Martin reignites ‘Game of Thrones’ finale feud: I was left 'out of the loop' - New York Post

Martin launched the series called “A Song of Ice and Fire” in 1996, with the first book in the series titled “A Game of Thrones.”.

Both Benioff and Weiss used Martin’s books as a jumping-off point — until they ultimately caught up with the author’s series in 2011, with the book “A Dance with Dragons.”.

To this day, the writer has completed and published just five of the seven books planned for the “A Song of Ice and Fire” series.

Martin has said he was busily at work on the forthcoming sixth installment, “The Winds of Winter,” while the final three seasons of “Game of Thrones” was being shot.
