If you’ve been watching HBO’s Game of Thrones, then you’ve already been treated to some spectacular sights.

It seems George R.R. Martin is not content to let HBO be the final word on the visual splendor of Westeros, however. His new book The World of Ice & Fire: The Untold History of Westeros and the Game of Thrones, released this week, gives Game of Thrones fans the chance to see visions of Martin’s world that are much closer to what he intended.

In an interview at The Huffington Post, Martin explains why there are so many pictures of castles:

I wanted accurate versions of these castles. We’ve had a number of different artists draw them on covers and on the fantasy like cards and games, and some of them have been beautiful images but not necessarily accurate to what I described.

The World of Ice & Fire, co-authored with Elio M. García, Jr. and Linda Antonsson, who run the site Westeros.org, isn’t just an art book, however. It’s a comprehensive history of the Seven Kingdoms — all the battles, betrayals, and back-room deals that lead to the events of Martin’s novels. It includes full family trees for Houses Stark, Lannister, and Targaryen; detailed histories of the cultures of Westeros; and more than 170 pieces of original art and maps, many in full-color.
