“Games of Thrones” season 6 is about to premiere in April but the book, “Winds of Winter,” where the season is supposed to based on has yet to be released.

GoT is now at a point where the fantasy drama has caught up with the novels, MovieWeb reported. However, avid fans still eagerly waiting with for “The Winds of Winter” and are still hoping it will come out before “Game of Thrones” season six premieres. Some fans even expressed concern that author George R.R. Martin will reach the end of his own mortality before finishing his novel, Screen Rant wrote.

Martin, who is now 67 years old, may reach his own mortality before finishing his novel. ScreenRant noted that with Martin’s age and the pace of production, such is not that all improbable.

“Game of Thrones” debuted on HBO the same year Martin’s book five was released. Now, five seasons of the show have passed and “Game of Thrones” Season 6 is about to premiere, but there is no new book to speak of yet.

According to Screen Rant, GRRM was recently asked on his Livejournal whether “A Dream of Spring,” the final novel in the “A Song of Ice and Fire” series, would hit bookshelves prior to “Game of Thrones” final season on TV.  The author hinted that he won’t be done with his story until at least 2020.

Martin added the HBO series will have to run 10 seasons before he can finish with all of the “Ice and Fire” books.

In all honesty, Martin said the world is likely to be able to read “A Dream of Spring” at the end of this decade.

The author earlier issued an apology for the delay of “Winds of Winter. “You’re disappointed, and you’re not alone. My editors and publishers are disappointed, HBO is disappointed, my agents and foreign publishers and translators are disappointed … but no one could possibly be more disappointed than me,” wrote Martin in his blog.

He also said he had canceled a number of appearances and even skipped writing an episode of “A Game of Thrones” to focus on “The Winds of Winter.”
