Avid followers of the “Game of Thrones” series have been impatiently waiting for the sixth installment of George RR Martin’s “A Song of Ice and Fire” series. The veteran author recently teased the possible release date of “The Winds Of Winter” novel.

Veteran author writes much slower than before

The Christian Post reported that George RR Martin is still keeping details about [VIDEO]The Winds of Winter” under wraps.

The news outlet claimed that the 68-year-old author is still uncertain whether or not he can launch the highly-anticipated book before 2017 ends.

"I did not start to write slower over the years. I was working on the first book for six years and four years on the second one,” Martin previously said in a statement. “These are not 1.5k pages like mine, but, for example, 500. In addition, I have not become younger. Age does not add enthusiasm,” he went on.

While working on “The Winds of Winter,” George RR Martin also revealed that he already started writing a Westerosi encyclopedia called “Fire and Blood” at the same time. He even said that the two books might be published together in 2018.

Martin is also finishing the scripts of the five potential spin-offs of the popular “Game of Thrones” TV series aside from writing novels.

The veteran writer previously revealed that he hired four writers – Carly Wray, Brian Helgeland, Jane Goldman and Max Borenstein – to help him complete his new projects.
