Id been promising this book to my goddaughters for decades, Diaz tells EW.

And, he says, I had no childrens books growing up, not really.

By the time I learned English, I had missed the whole picture-book moment.

ENTERTAINMENT WEEKLY: Why did you decide to write a childrens book?

And how did you approach it?JUNOT DIAZ: It was long overdue.

Id been promising this book to my goddaughters for decades.

Jacqueline Woodsons work was an immense help.

And then I began to write and throw away and write and throw away until something stuck.

This is a personal story youre telling.

My mother didnt read to me as a kid, not in the D.R.

or the U.S. her generation didnt grow up with that tradition, she didnt know better.

By the time I learned English, I had missed the whole picture-book moment.

Immigrant stories are of particular political significance right now.

Conservatives have spent decades demonizing and criminalizing what is best about this country: our immigrant and refugee communities.

Its not the reason I wrote the book, but I would happy for this side effect nevertheless.

Where did the inspiration for Lola come from?

How would you describe her?Lolas a composite of my goddaughters.

Shes smart without having to show off and creative as all get-out and more curious than Ill ever be.

She also had something that I didnt really have growing up in the United States a loving community.

(I definitely had a community, but I wouldnt say it was all that loving.)

Above all else, this is what I wanted to give to any kid I had a loving community.

In the end I never had kids, so I gave it to Lola.

The communities inIslandbornfeel authentic and vibrant.

How did you go about developing them?

We are brave like that.
