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: " 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 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.
