Michelle Obama's 'Becoming' Becomes 2018's Fastest-Selling Book, Says Barnes & Noble

The former first lady's memoir recorded the most first-week sales of any adult book in more than three years.

Former first lady Michelle Obama can now add best-selling author to her list of titles.

According to bookseller Barnes & Noble, her memoir Becoming is officially the fastest-selling book of 2018. The book, which details moments in Obama's life, ranging from her childhood in Chicago to her time in the White House, sold more copies in its first week than any other work released in 2018 — marking the most first-week sales for an adult book in more than three years.

Becoming has surpassed Bob Woodward's Fear: Trump in the White House for the 2018 title, while the only book in recent history to sell as many first-week copies as Obama's is Go Set a Watchman, Harper Lee's posthumous prequel to the classic To Kill a Mockingbird that published in July 2015.

“We knew Becoming was going to be one of the biggest books of the year, but it has now officially had the best first week of sales of any book in 2018, and is among the fastest sellers in Barnes & Noble history,” said Liz Harwell, senior director of merchandising, trade books at Barnes & Noble. “This is definitely the must-have book of the holiday season.”

Since the memoir's release, Obama has launched an American tour, booking talk shows and selling out arenas across the country to discuss her work. During her latest stop at Washington's Capital One Arena, Obama's husband, Barack Obama, made a surprise appearance to support his wife. The crowd rose to its feet as the former president took the stage to praise Obama as a woman and mother.
