Strong sales of adult fiction were not enough to prevent unit sales of print books from falling 1.2% in the week ended Sept. 11, 2021, compared to the similar week last year, at outlets that report to NPD BookScan. Three new releases helped drive up sales of adult fiction 20.9% over the week ended Sept. 12, 2020. Sally Rooney’s Beautiful World, Where are You was #1 on the category list, selling nearly 40,000 copies. And Kohei Horikoshi’s My Hero Academia, Vol. 29 and Forgotten in Death by J.D. Robb each sold more than 28,000 copies. Adult nonfiction had three new books with decent debut sales, but they couldn’t compete with the slate of nonfiction titles that came out last year at this time, including Michael Cohen’s Disloyal, which sold about 163,000 copies, and Think Like a Monk by Jay Shetty, which sold nearly 67,000 copies. In the most recent week, American Marxism by Mark Levine stayed #1 in the category, selling more than 34,000 copies. David Rubenstein’s The American Experiment was #2, selling almost 15,000 copies, while This Bright Future by Bobby Hall and Countdown bin Laden by Chris Wallace each sold more than 14,000 copies in their first week. YA fiction sales were up 13.6%. The Hawthorne Legacy by Jennifer Lynn Barnes was #1 in the category, selling more than 19,000 copies in its first week. Two other new titles had good debuts: Liz Braswell’s What Was Once Mine sold more than 10,000 copies, and Sharon Cameron’s The Light in Hidden Places sold nearly 8,000 copies. Juvenile fiction sales slipped 0.4% compared to a year ago, when Dav Pilkey’s Grime and Punishment sold more than 126,000 copies.
