“Y’all, this book almost killed me dead, but I did it,” she wrote.

Now she’s shifting to her first nonfiction book, and second overall.

“It’s a really intense topic,” Machado tells EW.

“It was difficult emotionally.

And it required me to stretch my comfort zone way past where I normally do.

I’m not a historian.

I’m not a traditionally trained journalist.

[It] took a lot out of me.

The book also took much longer than I thought it was going to.

So it felt like a space very rich for exploration.”

(“It’s just exhausting,” she admits.)

She barely worked on a schedule, writing “as things moved” her.

“I spent one week where I barely wrote a word except from taking notes.

I was just reading through papers and articles and all kinds of things.

There were just a lot of steps to it.”

The memoir publishes Oct. 1, and isavailable for pre-order.
