Kim Hyun Sook and Ryan Estrada, the co-authors of the Eisner-nominated Banned Book Club and the followup No Rules Tonight, have a third graphic novel lined up for October release. Good Old Korean Spirit is set in the same world as the first two and is based on Hyun Sook’s experiences as a student during Korea’s authoritarian regime of the 1980s. However, Good Old Korean Spirit is a lighter, standalone story about a group of teens who are reluctantly sent off to the countryside to spend the holiday of Daeboreum with their elders. The teenagers, all members of a dance club, are focused on music and budding romances, while the grannies speak mysteriously about ceremonies and evil spirits. The book is rated for ages 12 and up, and Penguin Workshop will publish it on October 7, 2025, as a hardcover with an MSRP of $24.99 and a paperback with an MSRP of $17.99.

“Korea did not come together to fight for freedom until everyone realized they were on the same side,” Hyun Sook said in a statement accompanying the announcement. “Our book is about a group of grumpy old grannies who invite a group of troublemaking teens to their farm. Everyone is at odds, and the teens are terrified that the grannies will uncover their secret banned book club and turn them into the police. But they quickly learn that the grannies have secrets of their own, from their own experiences to ghost stories, folk tales, and legends about what haunts the farm. "

“When Hyun Sook and I started writing books about her experiences in a dangerously divided society under an authoritarian government that fostered distrust as they assaulted and imprisoned those who exercised free speech, freedom of assembly, and freedom to read, it was a cautionary tale,” said Estrada. “But as the world started to mirror the history we were writing about, we decided that we'd better write a book inspired by how Korea saved itself. Good Old-Fashioned Korean Spirit is about generation gaps, culture clashes, secrets, and other reasons that cause a persimmon orchard full of people to distrust and fear one another. But the more they communicate and collaborate, the more they realize that we're all in it together."

Estrada and Hyun Sook, who are married and live in South Korea, had planned to come to the U.S. to promote the book this year but decided not to out of concern for Hyun Sook’s safety (see  “Eisner Nominated ‘Banned Book Club’ Creators Speak Out on Canceled Book Tour”).
