The New York Times best-selling author's goddaughters served as the inspiration for the "Islandborn" picture book.
He explained to The New York Times that when his goddaughters were young, they asked him to write a book with characters that resembled them.
"Behind their request was this longing for books and stories that resonated for them and included them, and opened a space where they could be protagonists in the world," he said.
And although they asked him for this 20 years ago, Díaz is a man of his word.
It's also a story that Díaz relates to on a personal level, as he's seen a lack of representation in his industry.
"It ties to my own Dominican immigrant identity. It was an absence I felt acutely," he noted.
The story follows a Dominican-born girl named Lola, who is growing up in Washington Heights and trying to reconnect with her island roots thanks to a school project.
It will include themes of immigration, multiculturalism, and belonging. Pretty incredible topics to introduce to young readers, right?
It's exactly what the world needs: diverse stories.
Thank you, Díaz!
