While it may seem easy to make a joke about needing all the red pens you can find given Game of Thrones bloody history, all that is being revealed about the coloring book due this October from Bantam that George R.R. Martin is overseeing is that it “will feature 45 original black and white illustrations, inspired by characters, scenes, locations and other iconic images from Martin’s wildly successful ‘A Song of Ice and Fire’ series.”

The art will be drawn by “world renowned fantasy illustrators” Yvonne Gilbert, John Howe, Tomislav Tomic, Adam Stower and Levi Pinfold, Bantam told Time magazine.

An Unofficial Game of Thrones Coloring Book appeared recently and adult coloring books are enjoying a surge in popularity. The Guardian reports that 3 of the top 20 books being sold on amazon.co.uk are coloring books.

It looks like the book when it is released will be priced at $15.
