However, there are other theories on why the book is taking so long, with some suggesting the poor reception of the final series of Game of Thrones has forced Martin to change his story plans, and make The Winds of Winter more palatable for fans,
One A Song of Ice and Fire expert BryndenBFish, who has spoken out before about the the upcoming book, has revealed another reason why the book may be delayed slightly.
He tweeted: “One of the strangest things about TWOW [The Winds of Winter] is that GRRM wasn’t planning on having the Battle of Ice occur on-page.
“Like he seems to have decided very, very late in writing ADWD [A Dance with Wolves] that he should write it — like we’re talking a few months before he finished ADWD.
