HBO have announced that a companion book for the Game of Thrones TV series will be released in the autumn.
Inside HBO's Game of Thrones is a volume that mixes fictional background details with behind-the-scenes information, maps, family trees and interviews with castmembers. The book is 192 pages long and will feature over 300 colour photographs and illustrations, along with eight gatefold images. The book is written by Bryan Cogman, the show's 'keeper of the mythos' and writer of two episodes of the TV series. George R.R. Martin supplies a preface and showrunners David Benioff and D.B. Weiss an introduction. The book will be published on 19 September this year by Chronicle Books in the USA. It will be available in the UK via the British HBO merchandise site.
The book should not be confused with The World of Ice and Fire, an in-universe companion volume to the book series, which will likely be published in 2013.
