Louise Penny’s 20th Chief Inspector Gamache mystery, The Black Wolf, ranks #2 on the hardcover fiction list. Our starred review praised it as “exemplary.” In March, Penny, a Canadian author, canceled her planned U.S. tour, citing “the ongoing threat of an unprovoked trade war” and “other things the U.S. president is doing that make visiting the U.S. unpalatable.” As a sign of cross-border solidarity, she concluded her Canadian tour with two sold-out events at the Haskell Free Library & Opera House, located between Vermont and Quebec.
Eisner-nominated manga creator Mokumokuren’s The Summer Hikaru Died volume six debuts at #6 on the trade paperback list. This coming-of-age horror series features queer themes. Yen Press began English translations in 2023, and Netflix premiered the anime adaptation in July 2025.
Ree Drummond’s The Pioneer Woman Cooks: The Essential Recipes tops the hardcover nonfiction list. This is her ninth cookbook, maintaining her broad popularity. Her previous book, The Pioneer Woman Cooks: Dinner’s Ready!, has sold nearly 304,000 print copies since its release two years ago.
