Unit sales of print books fell 13.9% in the week ended Jan. 8, 2022, compared to the first week in 2021, at outlets that report to NPD BookScan. The only two categories that had increases over the week ended Jan. 9, 2021, were adult fiction, which was up 4.5%, and YA fiction, which had a 4.2% gain. Adult fiction sales were helped by two authors who are TikTok favorites. Colleen Hoover had the first-, third-, and fifth-bestselling books in the category, led by It Ends with Us, which sold more than 41,000 copies. The Seven Husbands of Evelyn Hugo by Taylor Jenkins Reid was #2 on the list, selling more than 25,000 copies. The top-selling new release was Danielle Steel’s Invisible, which sold almost 19,000 copies. The top-selling new book in YA fiction was Heartstopper, Vol. 4 by Alice Oseman, which sold more than 10,000 copies. Unit sales fell 20.5% in both the adult nonfiction and juvenile nonfiction categories. The decline in adult nonfiction had more to do with softness throughout the category rather than weakness at the top of the bestseller list. In the most recent week, Atomic Habits by James Clear was #1, selling about 48,000 copies—slightly more than the 47,000 copies Barack Obama’s A Promised Land sold in the similar week last year. The top-selling new book in the category was Unthinkable by Jamie Raskin, which sold almost 19,000 copies. Juvenile nonfiction sales fell despite a new #1 title: My Little Golden Book About Betty White by Deborah Hopkinson sold almost 34,000 copies, up from about 1,000 copies in the prior week. White died December 31.
