Jason Reynolds found a novel way to celebrate Giving Tuesday.

The author of books for young readers bought all of his own books from independent Washington, D.C., bookstores, so people could get them free of charge, WAMU reports.

“So...it’s giving Tuesday,” Reynolds tweeted on Tuesday. “And I’ve bought out just about all of my inventory in DC.” He then encouraged readers to contact bookstores like Solid State Books, Politics and Prose, Mahogany Books and Sankofa to see if the books were still available.

“ALL I ASK, is that you not be greedy,” he added. “And also, if you’re picking one up, and it’s the last, and there’s a kid who wants it, PLEASE let it go. Love y’all.”

Reynolds, who serves as the Library of Congress’ national ambassador for young people’s literature, is known for his middle-grade and young adult novels like When I Was the Greatest, Long Way Down, and Look Both Ways. His most recent book, Stamped, a collaboration with Ibram X Kendi, was a finalist for the Kirkus Prize for Young Readers’ Literature earlier this year.

“It kind of works for everybody, where people can go get anything they want for free, since I bought them all,” Reynolds told WAMU. “And then while they’re in the store shopping or picking up their books, maybe they’ll grab something extra.”

One bookshop grateful for Reynolds’ generosity was East City Bookshop, which tweeted a photo of a young reader holding a copy of Long Way Down.

“This is Zuri and her mother, the first people to pick up some of [Reynolds’] books he so graciously donated,” the bookstore wrote. “Thank you so much Jason!”
