"The Winds of Winter" is one of the most highly anticipated books this 2015. It will be the sixth installment in George RR Martin's epic novel "A Song of Ice and Fire" which is the basis of HBO's "Game of Thrones" TV Series. The author reveals his plans in ending his epic novel to the show's producers in order for the show to be on schedule.

Nikolaj Coster-Waldaue, the actor who portrays Jamie Lannister in the "Game of Thrones", revealed that George RR Martin has already finished writing "The Winds of Winter" and there is a definite ending already planned for "A Song of Ice and Fire" novel.

The actor said in one of his recent interviews that "[The show bosses] know as much as George R.R. Martin knows [about the story]," explaining that "He hasn't written the books, but he knows how he wants it to end. Well, I think he's written one of them now. I don't know when it comes out, but I'd assume soon."

"The Winds of Winter" may still be released this 2015 since George RR Martin is now back to work on his masterpiece and his publisher reveals that the length of his last two books is over fifteen hundred pages in length.

In related news, the "Game of Thrones" TV series may have a different storyline considering that "The Winds of Winter" and "A Dream of Spring" will have a delayed release compared to the scheduled broadcast of the remaining Season of the TV Show. Nikolaj commented that "All the details, [the showrunners are] going to have to come up with them themselves, It's going to be interesting because I think the show is going to finish before the last book comes out. There'll be quite a big difference when it does."

"Game of Thrones" Season 5 will be back on air this April 12 and fans have been speculating a lot on the possible ending of the show which includes the following:

• Daenerys will claim the Iron Throne after being successful in raising her army and conquering Westeros. However the kingdom will be mostly desolate due to the destruction caused by the war;
• Jon Snow, Daenerys, Tyrion and Jamie will have a final clash but not all of them will survive;
• Jon Snow and Daenerys will join forces and are rumored to be romantically involved. Fan theories also suggests that Jon Snow is the son of Ned Stark's sister Lyanna and Prince Rhaegar Targaryen which makes him an heir to the throne.

"The Winds of Winter" is the sixth book in George RR Martin's "A Song of Ice and Fire". The Epic novel will have a different ending compared to HBO's "Game of Thrones" TV adaptation.
