Jet City Comics, the new comic-publishing imprint of Amazon, have picked up the reprint rights to George R.R. Martin's Dunk and Egg graphic novellas. They will be reprinting The Hedge Knight on 5 November 2013 and The Sworn Sword on 21 January 2014. Random House will also be getting the gang back together to produce a new comic book adaptation of The Mystery Knight, for publication later in 2014.
In addition, HarperCollins Voyager in the UK have announced they will be publishing a British edition of Dangerous Women in December. This book will contain a new Song of Ice and Fire novella, The Princess and the Queen, about the civil war known as the Dance of Dragons. Martin is still hoping to publish The World of Ice and Fire in Spring 2014, though officially its release date remains November 2014.
No news on the Big One, unfortunately. The last word on the book from the start of the year was that it was about a quarter done and Martin had either completed or put aside all other projects (including the fourth Dunk and Egg story) to focus on it, later remarking he was making 'rapid progress' against the threat of HBO bearing down and catching up with him. Recent casting announcements for Season 4 of Game of Thrones seem to confirm that rather more of the Feast for Crows and Dance with Dragons storylines will be featured than first thought, meaning that they will likely reach Winds of Winter material by 2016, if not the end of the 2015 season.
