The fantasy romance book series A Court of Thorns and Roses, by author Sarah J. Maas, has sold over 13 million copies since the first book was released in 2015. Four years ago, Hulu, along with Battlestar Galactica showrunner Ronald D. Moore, optioned the book series for a television series adaptation. However, per Deadline, Hulu and 20th Television have axed the project.
