Despite the lack of a hot new title in the first nine months of 2017, print unit sales for the period were 2% higher than in the comparable timeframe in 2016. According to NPD BookScan, print units were 467.7 million in the January–September period, up from 460.6 million the previous year. While it is certainly possible that some fall books will ring up big numbers, the small sales gain to date has been driven by backlist titles. Only three of the year’s top 10 bestsellers to date were released in this calendar year. John Grisham’s Camino Island was the top new book, selling more than 528,000 print copies since its release in June to land at #5 on the year-to-date bestseller list. The other new titles on the top 10 list are Ruth Ware’s The Woman in Cabin 10 (#7) and Lilac Girls by Martha Hall Kelly (#10). The bestselling title so far this year is Milk and Honey by Rupi Kaur. Released in October 2015, the book has sold more than 706,000 copies in 2017, easily outdistancing the second-place book, Oh, the Places You’ll Go by Dr. Seuss.

Unit sales of print books fell 2% in the week ended June 3, 2018, compared to the similar week in 2017, at outlets that report to NDP BookScan. For the third week in a row, it was softness in the fiction categories that led to the decline. Unit sales dropped 5% in both the adult and juvenile fiction categories compared to the week ended June 4, 2017. In adult fiction, Stephen King’s The Outsider remained in first place on the category bestseller list, selling nearly 52,000 copies. Seven of the top 10 bestselling titles in the category were new books, with Shelter in Place by Nora Roberts at #2, selling more than 41,000 copies, while Christine Feehan’s mass market paperback Shadow Keeper was third, selling almost 21,000 copies. Overall, the top 100 adult fiction titles sold 100,000 fewer copies in the week ended June 3, 2018, than in the similar week last year. The 5% decline in juvenile fiction was also largely due to weakness among the top 100 bestsellers and not because of the release of a blockbuster title last year. Sales were particularly soft among young adult fiction titles, where sales of the top 100 books fell 29% in the week compared to 2017. In 2018, Victoria Aveyard’s War Storm was the top young adult fiction title, selling almost 7,000 copies, while a year ago Nicola Yoon’s Everything, Everything was #1 in young adult, selling more than 21,000 copies. Print unit sales rose by less than 1% in adult nonfiction over 2017. The category had a new #1 bestseller with Mordenkainen’s Tome of Foes, a D&D guide, in the top spot, selling more than 35,000 copies in its first week on sale. Another new book, Calypso by David Sedaris, landed in the third spot with over 21,000 copies sold.
