Planned novels and future (2011–present)
Martin believed in 2012 the last two volumes of the series would be large books of 1500 manuscript pages each. The sixth book will be called The Winds of Winter, taking the title of the last book of the originally planned trilogy. Displeased with the provisional title A Time for Wolves for the final volume, Martin ultimately chose A Dream of Spring as the title for the seventh book in 2006. Martin said in March 2012 that the final two novels will take readers farther north than any of the previous books, and that the Others will appear. Martin indicated he would not permit another writer to finish the book series.
The Winds of Winter is to resolve the cliffhangers from A Dance with Dragons early on and "will open with the two big battles that [the fifth book] was building up to, the Battle in the Ice and the Battle [...] of Slaver's Bay. And then take it from there." By the middle of 2010, Martin had already finished five chapters of The Winds of Winter from the viewpoints of Sansa Stark, Arya Stark, Arianne Martell, and Aeron Greyjoy, coming to around 100 completed pages. After the publication of A Dance with Dragons in 2011, Martin spent the remainder of the year on book tours, conventions, and continued working on his The World of Ice & Fire companion guide and a new Tales of Dunk and Egg novella. In December 2011, Martin posted a chapter from The Winds of Winter from the viewpoint of Theon Greyjoy; several other chapters have been made public since. Four hundred pages of the sixth novel had been written as of October 2012, although Martin considered only 200 as "really finished"; the rest needed revising. During the Guadalajara International Book Fair in Mexico in early December 2016, Martin offered the following hint as to the tone of this book: "There are a lot of dark chapters right now ... I've been telling you for 20 years that winter was coming. Winter is the time when things die, and cold and ice and darkness fill the world, so this is not going to be the happy feel-good that people may be hoping for. Some of the characters [are] in very dark places." Martin did not intend to separate the characters geographically again.
In 2011, Martin gave three years as a realistic estimate for finishing the sixth book at a good pace, but said ultimately the book "will be done when it's done", acknowledging that his publication estimates had been too optimistic in the past. In 2015 there were indications that the book would be published before the sixth season of the HBO show but in early January 2016 Martin confirmed that he had not met an end-of-year deadline that he had established with his publisher for release of the book before the sixth season. He also revealed there had been a previous deadline of October 2015 that he had considered achievable in May 2015, and that in September 2015 he had still considered the end-of-year deadline achievable. He further confirmed that some of the plot of the book might be revealed in the then-upcoming sixth season of Game of Thrones. In February 2016, Martin stated that he dropped all his editing projects except for Wild Cards, and that he would not be writing any teleplays, screenplays, short stories, introductions or forewords before delivering The Winds of Winter. In March 2020, Martin stated that he was writing The Winds of Winter every day, and in June he hoped to be done with it in 2021. In October 2022, Martin said that he had written approximately three quarters of the book. estimating that he had written approximately 1,100 to 1,200 pages, and had roughly 400 to 500 pages left. He gave a similar estimate in November 2023, saying that he was "struggling" with the manuscript. In July 2025 Martin said he had completed about 1500 manuscript pages, suggesting the book was nearly complete, but then later said in January 2026 that he only had 1,100 manuscript pages finished.
Martin is not firm about ending the series with the seventh novel. With his stated goal of telling the story from beginning to end, he will not truncate the story to fit into an arbitrary number of volumes. He knows the ending in broad strokes as well as the future of the main characters, and plans to finish the series with bittersweet elements where not everyone will live happily ever after. Martin hopes to write an ending similar to The Lord of the Rings that he felt gave the story a satisfying depth and resonance. On the other hand, Martin noted the challenge to avoid a situation like the finale of the TV series Lost, which left some fans disappointed by deviating too far from their own theories and desires.
In 2015, Martin said that he was not writing A Dream of Spring together with The Winds of Winter, and in early 2016, he said he did not believe A Dream of Spring would be published before the last season of the HBO show.
During a question-and-answer session at the 2016 Guadalajara International Book Fair, Martin emphasized: "I'm not going to tell you how I'm going to end my book, but I suspect the overall flavor is going to be as much bittersweet as it is happy."
In April 2018, Martin commented he had not started working on the book, and in November he said that after The Winds of Winter he would decide whether his next project after that would be A Dream of Spring, the second volume of Fire & Blood, or one or two stories for the Tales of Dunk and Egg.
In May 2019, Martin reiterated he had not started writing A Dream of Spring and would not do so before finishing The Winds of Winter.
Regarding A Song of Ice and Fire as his masterpiece, Martin stated he would never write anything on this scale again and would only return to this fictional universe in the context of stand-alone novels. He prefers to write stories about characters from other A Song of Ice and Fire periods of history such as his Tales of Dunk and Egg project, instead of continuing the series directly. Martin said he would love to return to writing short stories, novellas, novelettes, and stand-alone novels from diverse genres such as science fiction, horror, fantasy, or even a murder mystery.
