Amanda Gorman’s The Hill We Climb: An Inaugural Poem for the Country has become the first poetry book to reach No. 1 on USA Today’s bestseller chart, the newspaper reports.

The book contains the text of the poem that Gorman read at President Joe Biden’s inauguration in January. Gorman was 22 at the time of the event, making her the youngest inaugural poet in American history.

Her performance made her an instant superstar in the literary world. The day after the inauguration, two of her books, which hadn’t been published yet, hit No. 1 and No. 2 on Amazon’s bestseller list. And weeks later, she made history again as the first poet to ever read at the Super Bowl.

“I am so humbled and honored by this exciting news,” Gorman said in a statement to the newspaper. “I know that this best-seller spot comes from so many people deciding to bring my words into their lives. It makes me speechless to see poetry have such a ripple effect, and I’m excited to see more poets stand beside me on the best-seller list.”

On Twitter, Gorman revealed that The Hill We Climb “now has the biggest week 1 sales of any Poetry title ever published.”

“That rumble above is the sound of the poetry ceiling cracking,” she wrote. “Thank you thank you thank you to all the people who chose to bring my words into their lives.”

As of Monday morning, The Hill We Climb was the No. 3 bestselling book on Amazon. Two other books by the poet, including a poetry collection with the same title, are scheduled for publication in September.
