Last year’s success of Michelle Obama’s Becoming continues to hover over the 2019 holiday sales season. Released in November 2018, Becoming sold about 441,000 print units in the week ended Dec. 8, 2018, at outlets that report to NPD BookScan. In the week ended Dec. 7, 2019, the top-selling book in adult nonfiction (where Becoming is classified), The Pioneer Woman Cooks: The New Frontier by Ree Drummond, sold just over 43,000 copies. In second place last year at this time in adult nonfiction was The Point of It All by Charles Krauthammer, which sold more than 73,000 copies. Number two in the most recent week was The Blue Zones Kitchen by Dan Buettner, which sold more than 29,000 copies. As a result of the weakness atop the adult nonfiction list this year, sales of print units fell 7.3% in the week ended Dec. 7, 2019, in the category, compared to the similar week in 2018. The drop in adult nonfiction sales offset gains in the juvenile categories, resulting in an overall 1.3% decline in print unit sales in the week. Unit sales in juvenile nonfiction jumped 13%, led by the seasonal favorite The Elf on the Shelf by Carol Aebersold, which sold nearly 34,000 copies. Juvenile fiction sales rose 5.5% over 2018; Jeff Kinney’s Wrecking Ball (Wimpy Kid #14) took the top spot, with more than 90,000 copies sold. Print unit sales in adult fiction were flat with 2018. John Grisham’s The Guardians was #1 on the category list, with more than 40,000 copies sold, followed by Where the Crawdads Sing by Delia Owens, which sold more than 38,000 copies.
