Michelle Obama’s new book, Becoming, is now the best-selling book of 2018.

Penguin Random House announced Friday that the former first lady’s memoir has sold over 2 million copies in North America in hardcover, e-book and audio sales. Becoming sold a massive 725,000 copies on its first day in print, according to Entertainment Weekly.

Angie Thomas’ The Hate U Give and Watergate journalist Bob Woodward’s Fear: Trump in the White House were the two books  in the running to receive the year’s top-selling honor, but they were surpassed by Becoming, per EW.

Obama’s book topped the nonfiction best-seller lists in the UK, Germany, France, Italy and Norway, per Quartz.

In Becoming, Obama details her life growing up on the South Side of Chicago, meeting and falling in love with future president Barack Obama and balancing life as a working mother.

Obama is currently on a book tour and will be at London’s Royal Festival Hall today (Monday) speaking with writer Chimamanda Ngozi Adichie.

The new author announced that she had to cancel her tour dates for Paris and Berlin on Dec. 5 and Dec. 6 to attend the funeral of former President George H.W. Bush, who passed away in Houston on Friday at age 94.
