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

By the time my mother married my father, however, she knew all about the true nature of the dictatorship. Thousands had lost their lives in failed attempts to return the country to democracy. Family friends, whom she had assumed had dropped away of their own accord, turned out to have been disappeared. My father had been lucky. As a young man, he had narrowly escaped to Canada after the plot he had participated in as a student failed. This was to be the first of two escapes. That same year, 1937, El Generalísimo ordered the overnight slaughter of some eighteen thousand Haitians, who had come across the border to work on sugarcane plantations for slave wages.
