“Becoming,” the memoir by former first lady Michelle Obama, has emerged as the bestselling hardcover book in 2018, with 3.4 million copies sold, despite its November release.

According to stats released by NPD Bookscan, which tracks about 80 percent of the retail market, Obama’s book surged, with 712,000 sold in the week before Christmas. That even beat the sales following its Nov. 13 release, when its first-week sales hit a record 710,000 copies sold, according to Bookscan.

The robust numbers have to be a big relief to Penguin Random House, which bought the book in a two-book deal including a memoir by former President Barack Obama for a record-shattering $65 million.

Two other nonfiction books tied to examining the stormy tenure of President Trump also finished in the top 10. Michael Wolff’s “Fire and Fury” finished in fifth place, with 1,016,014 hardcover books sold. Bob Woodward’s “Fear” landed in seventh with sales of 972,750.

Children and young adult books also finished strong: “Girl Wash Your Face” by Rachel Hollis was in third for the year with 1,280,464 sold while Jeff Kinney’s “Diary of a Wimpy Kid: The Meltdown” landed in fourth with 1,144,649 and “The Wonkey Donkey” by Craig Smith was in sixth with 973,851 copies sold.

Eight and nine were held by “Dog Man and Cat Kid” by Dav Pilkey (716,329) and “You Are a Badass” by Jen Sincero (712,990). “The President Is Missing,” by former President Bill Clinton and James Patterson, held down No. 10 (703,230).
