If you haven't read Kingsolver's The Poisonwood Bible, I highly recommend it. It tells the story of an evangelical minister from Georgia who takes his family to live in the Belgian Congo as missionaries. It's one of those amazing books that has a lasting impact on you...or at least it did on me.
Kingsolver has also written non-fiction, including a book about her family's attempt to eat local for an entire year. In the book Animal, Vegetable, Miracle: A Year of Food Life, she chronicles their food production and consumption on a farm in Virginia.
Are you a fan of her writing?
