Unit sales of print books fell 3.6% in the week ended Sept. 18, 2021, from the comparable week in 2020, according to NPD BookScan. Sales in adult nonfiction fell 11.2% from the week ended Sept. 19, 2020. Last year, Bob Woodward’s Rage sold nearly 345,000 copies in its first week, while Blackout by Candace Owens sold more than 70,000 copies. Several new nonfiction titles had respectable sales, but not at the same level as last year. An Unapologetic Cookbook by Joshua Weissman was #1 on the category list, selling more than 58,000 copies. Heather Heying’s A Hunter-Gatherer’s Guide to the 21st Century sold more than 17,000 copies, putting it in third place. Juvenile nonfiction sales dropped 12.1%, as interest in educational titles that can be used at home continued to cool. Adult fiction sales jumped 16.6% over last year, driven by the release of three new titles. Apples Never Fall by Liane Moriarty was #1, selling more than 47,000 copies, followed by Harlem Shuffle by Colson Whitehead and Enemy at the Gates (the latest in the Mitch Rapp series created by Vince Flynn and now written by Kyle Mills), which sold 29,000 and 28,000 copies, respectively. YA sales increased 16.8%, with backlist leading the gain. They Both Die at the End by Adam Silvera was #1, selling more than 11,000 copies. The small decline in juvenile fiction came despite two decent debuts. Boo! Guess Who, Elmo by Matt Mitter sold about 17,000 copies, and The Last Kids on Earth and the Doomsday Race by Max Brallier sold more than 14,000 copies.
