Fict - In the Time of the Butterflies by Julia Alvarez

Amazing fictional account of real-life heros - the Mirabel sisters -  in the Dominican Republic of the 1960's.  Their code name was "las mariposas",  Spanish for butterflies.

The communist movement was sweeping 3rd world countries, Fidel Castro was mobilizing rebels in Cuba, private property and businesses were being confiscated, and people were disappearing in the night. 

Told from the perspective of the lone surviving sister, it's a  moving story of  family ties and relationships during the rise of the brutal Trujillo dictatorship.  Families everywhere had hard choices to make for themselves, their businesses, and their futures.

 Perfect blend of history and drama.
