However, fans are still waiting for Martin to finish writing the books Game of Thrones was based on – the sixth book, The Winds of Winter, has been anticipated since the previous instalment was published in 2011. Martin has repeatedly cited both his workload and travel as preventing him from finishing what will be the penultimate book in the series.

Martin is also working on a Game of Thrones Netflix film, and Broadway play. The last Game of Thrones book, A Dance with Dragons, was published in July, 2011. Martin has promised the sixth, The Winds of Winter, would be published next year, every year since 2015.
