Martin’s long-awaited book, The Winds of Winter, has become one of the most famous delays in modern publishing. Initially, Martin hoped to finish the book quickly, using content cut from the previous novel, but progress has been slow. According to Martin, the manuscript is expected to be over 1,500 pages, and as of late 2023, he estimated he had completed around three-quarters of it. In April 2015, Martin revealed he hoped the novel would be done before Game of Thrones Season 6 aired. Martin even skipped convention appearances and other projects to concentrate on writing.
