It sounds crazy, and the person who came up with this theory is well aware of that.
But what if Martin finished The Winds of Winter and is already working hard on A Dream of Spring?
As out there as it sounds Nerdist do have some pretty good reasons to make such a seemingly outlandish claim.
First off they point out that in 2012 – six years ago – the Game of Thrones author said he had already completed chapters of the sixth book in 2010.
Not only that, but that he hoped The Winds of Winter would be released in 2014 – yes that’s four years ago.
By early 2015, Martin was saying he reckoned it could be completed in just a few months.
Then later that year he was hopeful it would arrive in early 2016, but that year came and went.
And by January 2017 the author said he intended for the novel to arrive later in the year and now we’re looking at no earlier than 2019.
Surely there’s something fishy going on when you say you’re only a few months from finishing a book and that was almost five years ago?
The theorist reckons there’s a reason beyond waiting for HBO’s Game of Thrones TV show to end.
Instead they suggest he’s not releasing The Winds of Winter until he finishes A Dream of Spring – the series finale – “in case he runs into any logistical problem with the story.”
They added: “A Song of Ice and Fire boasts an incredible large universe, with so many characters and plots that it doesn’t seem possible to keep track of all of them.
“The closer he gets to the end, the fewer opportunities Martin will have to work his way out of any snags in the canon; less story time limits where he can go.
“Martin may be holding onto The Winds of Winter in case it needs some narrative tweaking based on a problem he hits toward the end of the Song of Ice and Fire epic.
“He obviously wants to nail the landing on the defining work of his career, and this could be the best way to ensure that happens.”
