With all but one category posting double-digit gains, unit sales of print books rose 17.5% in the week ended Sept. 5, 2020, over the comparable week in 2019, at outlets that report to NPD BookScan. Sales in the juvenile fiction category rose 30.6% over the week ended Sept. 7, 2019, due in large part to the release of Dav Pilkey’s Grime and Punishment (Dog Man #9), which sold more than 239,000 copies in its first week. The category also received a boost from another new Scholastic title, as Ann M. Martin’s Logan Likes Mary Anne! sold more than 32,000 copies in its first week. Unit sales in the YA fiction category jumped 43.4% over 2019. Cassandra Clare’s The Lost Book of the White, Vol. 2 sold nearly 13,000 copies in its first week, putting it in third place on the category list. Two other new releases added to the sales increase: Blood & Honey by Shelby Mahurin and American Royals II: Majesty by Katherine McGee each sold more than 10,000 copies. Unit sales in the juvenile nonfiction category rose 44.4% over 2019, due mainly to the educational titles that have dominated the list since the pandemic hit. One new addition was Rob Colson’s Engineer Academy Robotics, which sold nearly 16,000 copies in its first week. The adult fiction category had a 10% sales gain in the week, led by Louise Penny’s All the Devils Are Here, which sold almost 59,000 copies in its first week, placing it first on the category list.
