George R.R. Martin Said He's Struggling To Finish Next 'Game Of Thrones' Book

The fantasy author has described how challenging it's been to focus on writing following the popularity of the HBO TV show based on his work.

Martin wrote the first book in his Song Of Fire And Ice series in 1996 and released the fifth book -- A Dance With Dragons -- back in 2011.

But the final two books in the epic collection -- The Winds of Winter and A Dream Of Spring -- have been "forthcoming" for a while now.

Which could have something to do with the HBO series Game Of Thrones coming out in April 2011.

“I’ve been struggling with it for a few years,” he told the Guardian in a new interview.

The Winds of Winter is not so much a novel as a dozen novels, each with a different protagonist, each having a different cast of supporting players, antagonists, allies and lovers around them, and all of these weaving together against the march of time in an extremely complex fashion."

Martin said that after HBO created Game Of Thrones -- based on his series of books -- the writing process got a little trickier.

“The show has achieved such popularity around the world, the books have been so popular and so well reviewed, that every time I sit down I’m very conscious I have to do something great, and trying to do something great is a considerable weight to bear,” Martin said.

Martin said that once he gets into his writing groove, "the rest of the world vanishes".

"... And I don’t care what I’m having for dinner, what movies are on, what my email says or who’s mad at me this week because The Winds of Winter isn’t out -- all that is gone and I’m just living in the world I’m writing about.

"But it’s sometimes hard to get to that almost trance state.”
