[EX Q]: I really enjoyed this book. If you like novels that are vivid and descriptive, that clearly paint life of women in other countries and cultures, then this book is for you. It offers a glimpse of two very different families in El Salvador - rich coffee plantation land owners and peasant coffee pickers/servants. I specifically liked how Benitez had the action and every day life ~ with joy, sorrow, love, births, deaths ~ take place in the context of major historical events. I loved how the "telenovela" and its characters took on a life of their own. Anyone who has visited a Latin American country can vouch that they can really take a whole nation by storm! (Just think, how many people in America were waiting to see which David won American Idol?!) As a person of Salvadoran descent it served as middle-age introduction to the tumultuos and rich history of the country and it left me longing to learn more and reconnect with my roots.
[EX A]: Positive
