Inauguration Day poet Amanda Gorman is already a bestselling author on Amazon -- and her books aren't expected to be released for months. 

Hours after reciting “The Hill We Climb” at the swearing-in ceremony of President Joe Biden, the poet took to Twitter to reveal her unreleased books took the top two spots on Amazon.

“I AM ON THE FLOOR MY BOOKS ARE #1 & #2 ON AMAZON AFTER 1 DAY! Thank you so much to everyone for supporting me and my words. As Yeats put it: ‘For words alone are certain good: Sing, then,’” she tweeted Wednesday night.

Gorman’s book “Change Sings: A Children’s Anthem” was a No. 1 best seller in the Children’s Poetry section. “The Hill We Climb: Poems” was labeled the No. 1 best seller in the Books section.

The release of both books is scheduled for Sept. 21. The 22-year-old Los Angeles native made history Wednesday as the youngest person to ever read a poem at a presidential inauguration.

For Gorman, the moment wasn't only history-making but deeply personal. Like Biden, she struggles with a speech impediment. 

The poet credited “Hamilton” with helping her overcome her speech impediment. She referenced the hit Broadway musical in her inauguration poem.

“I would try to keep up with Leslie Odom Jr. as he’s doing this amazing rap, and I’d say, ‘If I can train myself to do this song, then I can train myself to say this letter,’” she told CNN’s Anderson Cooper. 

“And so that’s been a huge part of my own speech pathology. It’s why I included it in the inaugural poem.”

In “The Hill We Climb,” Gorman wrote: “History has its eyes on us,” which was a nod to Hamilton's “History Has Its Eyes on You.”

During an appearance on “Good Morning America” Thursday, Gorman was treated to a surprise message from the musical’s creator Lin-Manuel Miranda, who praised the young woman for her powerful poem.

“Good morning Amanda Gorman, it’s Lin-Miranda. Congrats again on yesterday,” he said.

“The right words in the right order can change the world, and you proved that yesterday with your brilliant piece. I’m so incredibly proud of you and I can't wait to see what you write next.” 

Miranda added: “Keep changing the world, one word at a time. You smashed it!”
