I'm listening to this as an audiobook and I'm guessing I'm about halfway through, but I feel justified in giving it 4 stars. I might add or subtract a star when I'm done listening to it.
I'm glad I'm listening to this one, rather than just reading it, but I will probably buy the book too. It's written in the first-person, alternating among 3 women in early-1960's Mississippi - 2 black maids and one young white woman who has just graduated from college and is seeing the community she grew up in in a new way.
The narrators bring them to life in a way that makes them even more vivid and real. I feel as if these characters are real people who are telling me their stories, not just fictional characters. So far, it's powerful and fascinating, and as well-narrated as it is well-written. Recommended listening or reading.
(Edit: I have finished listening to it and thoroughly enjoyed it, and I decided to add that 5th star.)
