(CNN) Michelle Obama's memoir "Becoming" has become the best selling book of the year in the United States, surpassing Michael Wolff's "Fire and Fury" and others.

Wolff's "Fire" was a publishing world sensation when it came out in January. To date it has sold 1,008,088 hardcover copies, according to NDP BookScan data.

All year long, it was the year's No. 1 political book. Its closest competitor was "Fear," by Bob Woodward, which came out in September and has sold 872,567 hardcover copies to date.

But "Becoming" outpaced them both in just a couple of weeks. BookScan shows 1,122,618 hardcover copies of Obama's uplifting memoir have sold since its November 13 release date.

That makes it No. 1 for the year. The year's No. 2 book in terms of hardcover sales is "Magnolia Table," a cookbook by TV star Joanna Gaines. "Fire and Fury" now ranks No. 3, followed by Rachel Hollis' self help book "Girl, Wash Your Face" at No. 4 and "Fear" at No. 5.
