George R.R. Martin, the Game of Thrones author, updated his blog Tuesday and shared with his readers that he hoped his new book, The Winds of Winter, would be released in 2021.

The Winds of Winter is the long-awaited sixth book in his series: A Song of Ice and Fire.

“I have to confess, after half a year of pandemic, quarantine, and social distancing, I am showing signs of cabin fever… half of which is quite literal in my case,” Martin wrote. “Yes, I am in an actual cabin in the mountains. No, I have no fever. Yay! For the present at least, I am healthy… for an out-of-shape guy of 71, at least… and doing all I can to stay that way.”

Martin continued in his post, “If nothing else, the enforced isolation has helped me write. 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. But no, this does not mean that the book will be finished tomorrow or published next week. It’s going to be a huge book, and I still have a long way to go …  I have bad days, which get me down, and good days, which lift me up, but all in all I am pleased with the way things are doing.”

The renowned author mentioned in his blog post that he was “heartbroken” that he had to cancel his trip to New Zealand for the 78th World Science Fiction Convention, as it will be held virtually this year. 

Martin also discussed how when he wrote the third book in the series, A Storm of Swords, he averaged writing 150 pages a month. “I fear I shall never recapture that pace again. Looking back, I am not sure how I did it then,” the author wrote.

As of now Martin is also working as an executive producer and co-creator for the upcoming Game of Thrones prequel series, House of the Dragon. Universal Cable Productions is also teaming up with Hulu to create two series based on Martin’s Wild Cards novels.
