This isn't just a very moving story about Henrietta Lacks and her family, but an interesting examination of race, class, and the path to adoption of modern laws regarding informed consent for research subjects and privacy of medical records. It's also an interesting scientific history of the HeLa cells themselves, why they are so unusual, and how they have been integral to the development of modern cancer treatments. The author treats sensitive subjects in a moving way that really draw you into the story, and I found myself rooting for the Lacks family to find justice and, more importantly, emotional closure.
