EXCLUSIVE: A series adaptation of Penn Cole‘s bestselling romantasy book Spark of the Everflame is in the works for the screen.

Hulu has taken in for development Everflame, a drama based on Cole’s first book in the popular romance fantasy series, The Kindred’s Curse Saga, from Death and Other Details co-creator Heidi Cole McAdams, Cole and 20th Television.

Everflame is set in a world where mortals live in poverty, subjugated by an elite race known as the Descended. When her mother goes missing, Diem Bellator suspects that the most powerful and most feared Descended in the kingdom – Prince Luther Corbois – may be responsible.  As she embarks on a search for answers, she becomes an unexpected force in the mortal rebellion against the Descended, and the center of an even more unexpected love triangle. 

McAdams serves as writer and executive producer, and Cole as producer. 20th Television is the studio.

“I’m thrilled to be working with Heidi Cole McAdams to adapt The Kindred’s Curse Saga,” said Cole. She truly understands the core messages of the series and what makes Diem’s story compelling. Heidi has an incredible eye for re-imagining the story for a visual medium while preserving the aspects of the books that readers love most, and her enthusiasm for collaboration makes her an author’s dream to work with. I have no doubt this adaptation will be as beloved to new audiences as it will be to the series’ passionate fanbase.”

McAdams served as the co-creator, executive producer, and co-showrunner of the Hulu mystery series Death and Other Details, which aired on the streamer in 2024. She’s repped by UTA and Jeff Hynick at Jackoway Austen Tyerman.

Cole is a New York Times, USA Today, Der Spiegel, and Globe and Mail bestselling romantasy author and attorney. Her The Kindred’s Curse Saga series follows healer Diem Bellator as the search for her missing mother pulls her into a growing civil war between the oppressed mortals of Emarion and the magic-wielding demigods known as the Descended. Originally self-published in 2023, Spark of the Everflame, the first book in the series, became an instant viral sensation on social media before being acquired by Atria Books and republished in 2024. The Kindred’s Curse Saga is Penn Cole’s debut series and has sold over three million copies worldwide in 18 languages. Spark of the Everflame has sold over one million copies. The highly anticipated final book, Burn of the Everflame, will be released on September 8, 2026. Cole is repped by WME and The Whalen Agency.
