The book itself promises to be fascinating, but what immediately captured me is that the readers are two of the women who voiced characters in the audio version of The Help that I just finished: Cassandra Campbell and Bahni Turpin. Campbell, a Caucasian woman, voices Henrietta as well as the (white) writer of the book, Rebecca Skloot. Bahni Turpin voices Lacks' daughter and was Minny in the audiobook of The Help.
If you're interested in The Help, I highly recommend the audio book. The voicing of the characters (mostly women) adds so much to the story, and while I usually prefer my novels printed, this was one that I LOVED in audio format. I downloaded mine from the Toronto Public Library, but it's widely available. A film version is in production and so I encourage those of you who want to read it/listen to it first to get busy!
