Unit sales of print books fell 4.1% in the week ended Dec. 10, 2022, from the comparable week in 2021, at outlets that report to NPD BookScan. The adult and young adult fiction categories both had sales increases over the week ended Dec. 11, 2021. Adult fiction sales were up 4.8%, driven by a number of Colleen Hoover titles. It Starts with Us was #1 in the category, selling more than 82,000 copies, followed by It Ends with Us, which sold nearly 59,000 copies. Lessons in Chemistry by Bonnie Garmus was in fourth place, selling almost 38,000 copies—the most the novel has sold in a week since its release in April, due to a surge in publicity driven by the news that Apple TV+ will adapt it into a series. Young adult fiction sales increased 1.8%. Holly Jackson’s A Good Girl’s Guide to Murder was #1, selling more than 13,000 copies. A new release, Scott Cawthon’s Somniphobia, was in the third spot on the list, selling just over 11,000 copies. Adult nonfiction sales declined 8.3%. Last year, Call Us What We Carry by Amanda Gorman was #1, selling about 176,000 copies. In the most recent week, Michelle Obama’s The Light We Carry was #1 in the category, selling nearly 91,000 copies. A new release, How to Meet Your Self by Nicole Lepera, sold nearly 37,000 copies, landing it in fourth place on the list. Juvenile fiction sales fell 3.6%. Jeff Kinney’s Diper Överlöde just edged out Dav Pilkey’s Collaborations for the top spot in the category by 450 copies, selling a total of 72,648 units.
