Read the excerpt from "A Genetics of Justice” by Julia Alvarez.

When the novel came out, I decided to go ahead and risk her anger. I inscribed a copy to both Mami and Papi with a note: "Thank you for having instilled in me through your sufferings a desire for freedom and justice." I mailed the package and—what I seldom do except in those moments when I need all the help I can get—I made the sign of the cross as I exited the post office. Days later, my mother called me up to tell me she had just finished the novel. "You put me back in those days. It was like I was reliving it all," she said sobbing. "I don't care what happens to us! I'm so proud of you for writing this book."

I stood in my kitchen in Vermont, stunned, relishing her praise and listening to her cry. It was one of the few times since l had learned to talk that I did not try to answer my mother back. If there is such a thing as genetic justice that courses through the generations and finally manifests itself full-blown in a family moment, there it was.
