Michelle Obama's book "Becoming" may have only hit the shelves today, but days before its release, the memoir shot to No. 1 on the Amazon best-sellers list, where many expect it to stay for a while.

Although many other political best sellers of the year have examined the Trump presidency, Obama’s book is expected to have large success due to her personal and honest reflection of her life.

From her own challenges with infertility to her hesitation to enter a life of politics, the former first lady held nothing back in the book.  

According to the Washington Post, Barnes & Noble announced Obama’s memoir has sold more pre-orders than any other adult book since Harper Lee’s “Go Set a Watchman” was published in 2015.

“We’ve already seen tremendous demand for ‘Becoming’ before it has even hit the shelves,” Liz Harwell, senior director of merchandising at Barnes & Noble, told the Washington Post. “Our stores across the country are ready for huge demand tomorrow for what will likely be the biggest book of the season during what has been a blockbuster publishing calendar.”

This week, Obama will make appearances on daytime shows for ABC, NBC and CBS to promote her book, an opportunity most authors and celebrities are rarely afforded.
