For five seasons, Game of Thrones was an adaptation of George R.R. Martin’s epic fantasy novel series. But by Season 6, the series has caught up with the books, so–for better or worse–the series’ showrunners finished the story themselves, with some guidance from Martin. But that doesn’t mean fans won’t eventually get another installment of the books. Martin has been working on the next volume, titled The Winds of Winter, for several years, and has now provided a new update on its progress, saying he is making progress and that it could be finished in 2021.
In a new post on his blog, Martin explained that the COVID-19 pandemic has given him time to work on the book. “The enforced isolation has helped me write,” he said. “I am spending long hours every day on The Winds of Winter, and making steady progress. I finished a new chapter yesterday, another one three days ago, another one the previous week.”
However, Martin was careful to explain that fans wouldn’t be able to read the book anytime soon. “This does not mean that the book will be finished tomorrow or published next week,” he stated. “It’s going to be a huge book, and I still have a long way to go.”
