Yup. Chelsea also has done an official cookbook for A Song of Ice and Fire (Game of Thrones), World of Warcraft, Hearthstone, and an unofficial one for Lord of the Rings (The Shire).
Some of the most fascinating recipes are inspired by fantasy, and I am sure this book won't disappoint. I love cookbooks based on fictional recipes and foods, and this one I am sure will fit well in my collection.
