The Handmaid's Tale

Margaret Atwood
The Handmaid's Tale is set  in the near future in the Repuplic of Giliead, a country that was formed when the United States was overthrown by  racist, chauvinistic, theocratic military coup.  The story is told from point of view of a slave named Offred (of Fred, referring to the man she serves) who is a "handmaid" – a woman kept for reproductive purposes by the ruling class.   Margaret Atwood explores many social issues including:   gender roles, reproduction and sexuality, caste and social classes, and religious fundamentalism.  The author gives the reader a  thought provoking view into a future society.
This book would make an excellent choice for a book discussion group as it could lead to spirited discussion on many issues and provokes "What If" thinking.
