George R.R. Martin has confirmed in an interview with the Chapters Indigo blog that he has signed a deal with Bantam to release a collection of his Dunk and Egg stories. This first volume will collect the first four short stories into one book, but there will be more.
The collection will include The Hedge Knight, The Sworn Sword, The Mystery Knight and the forthcoming fourth story, The She-Wolves (a description of the story, maybe not even a working title at this stage). The fourth story will be published in Dangerous Women, a new anthology due in 2012, so I assume the Dunk and Egg collection will follow in 2013.
The stories follow the adventure of Ser Duncan the Tall, a hedge knight of rude birth, and his very unusual squire, Egg, as they have adventures across the Seven Kingdoms approximately ninety years before the events of A Game of Thrones. Along the way they become embroiled in the doings of kings, princes and rebels, and inadvertently have a major impact on the history of Westeros.
Excellent news. These stories are pretty cool and it'll be great to have them in one volume.
