George RR Martin overseeing ‘Game of Thrones’ coloring book

NEW YORK (AP) — George R.R. Martin is joining the adult coloring book game.

Bantam announced Monday that Martin will be overseeing the release of the “Game of Thrones Coloring Book,” featuring 45 new black and white illustrations by leading fantasy illustrators that are inspired by his “A Song of Ice and Fire” novels.

The book is scheduled for release this fall and represents another interim project from Martin as his millions of fans await the next installment of his series. Last year, Martin collaborated on “The World of Ice and Fire: The Untold History of Westeros and the Game of Thrones,” an illustrated guide.

Adult coloring books have been one of this year’s hottest genres, led by Johanna Basford’s “Enchanted Forest” and “Secret Garden.”
