Those who have read the books from "A Song of Ice and Fire" have many gripes about how their beloved series has been for television, one of which involve inaccuracies in how characters look. Never fear, purists! You now have the chance to give Tyrion his characteristic mismatched eyes or Daenerys' silver-blonde hair, thanks to the official "A Game of Thrones" coloring book.

Coloring books have been growing in popularity among adults looking for a simple activity to help them de-stress and unwind. There's nothing simple, however, with the "Game of Thrones" coloring book, as it features intricate details in every black-and-white page created by renowned illustrators like Levi Pinfold, Adam Stower, Tomislav Tomic, John Howe and Yvonne Gilbert.

Offered by Penguin Random House, the coloring book will be made up of 45 pages of exclusive illustrations, each one eye-popping and vivid, even without color.

"Fans of this blockbuster saga can fill in the blanks and marvel as this meticulously imagined universe comes to life ... [a] unique collector's item [expanding] the reach of an international phenomenon with flying colors."

Given George R.R. Martin's penchant for unexpected deaths and dramatic murders, however, investing in a number of red crayons and pens may be in order.

Coloring is generally associated with children but more and more adults are turning to the activity to take advantage of its benefits, namely generating wellness and quietness and stimulating areas of the brain related to creativity, the senses and motor skills. In psychology, Carl Jung was one of the first to utilize coloring as a means of relaxation, tapping into mandalas, circular designs originally from India featuring concentric shapes.

Grabbing a coloring book can help a person relax because the activity allows an individual to focus on a certain task instead of their worries, all while taking them back to their childhood which is normally filled with wonderful, definitely less stressful memories.

Adults taking on coloring is nothing exactly new but it is only recently that coloring books specifically tailored to adults are being released. For maximum effect, Antonio Fraguas, also known as Spanish cartoonist Forges, recommends using crayons instead of pen markers. Of course, you are free to use whatever coloring tool you prefer as using what you are comfortable with will help you relax.
