For the week ended Feb. 13, 2021, unit sales of print books increased 21.3% over the week ended Feb. 15, 2020, at outlets that report to NPD BookScan. It was the second consecutive week that unit sales rose by more than 20% over the comparable week last year. The increase was accomplished without the benefit of a big new hit and once again reflected strength across all major categories as well as big gains for backlist titles. The YA categories had the strongest gains, with nonfiction unit sales jumping 71.7% and fiction up 49.3% over 2020. Two anti-racist books—Stamped by Jason Reynolds and This Book Is Anti-racist by Tiffany Jewell—led the increase in YA nonfiction. We Were Liars by E. Lockhart topped the YA fiction list, selling almost 12,000 copies. Juvenile fiction sales rose 25.1% over 2020, and Llama, Llama I Love You by Anna Dewdney was #1 on the category list, selling about 38,000 copies. Juvenile nonfiction sales were up 24.1%. Little Leaders: Bold Women in History by Vashti Harrison was the most popular book in the category, selling more than 10,000 copies. The overall top-selling new title in the week was Walk in My Combat Boots by James Patterson and Matt Eversmann, which sold more than 30,000 copies. The success of Walk helped to drive up unit sales in the adult nonfiction category by 14.5%. Adult fiction sales rose 28.6%, helped by the release of J.D. Robb’s Faithless in Death, which sold nearly 30,000 copies.
