I took a DNA test for my granddaughters because something in my blood told me my son wasn’t their father. I thought I would expose my daughter-in-law, but the results pointed to someone much closer to home. The envelope arrived on a Tuesday, while I was heating tortillas on the griddle. Mateo, my son, was smiling at me from a photo on the wall. And when I read the first line, I felt my entire world collapse.

Mateo stood up.

I had never seen my son with that look before.

Julian stopped smiling.

“What’s with you?”

Mateo walked toward him and slapped the results onto his chest.

“Read it.”

Julian looked at the paper. First, he pretended not to understand. Then his eyes hardened.
