In a merger of a newly popular genre and a blockbuster series, later this year Bantam is releasing an adult coloring book inspired by George R.R. Martin's Song of Ice and Fire novels--which are the basis for HBO's Game of Thrones series. According to the AP (via the New York Times), the book will have 45 black-and-white illustrations by "leading fantasy illustrators." (Use of the book may require several extra red crayons!)
Martin's most recent book in the Song of Ice and Fire series, Dance of Dragons, was published in 2011, and fans are eagerly awaiting volumes six and seven.
