I read this some time ago, before I started on GR, and I'm glad I stumbled across it again because it is just so good and worthy of all 5 stars. Depressing in some ways, yes. There are definitely lessons to be learned from Henrietta's story, from what the medical establishment of the time did to her & her legacy (even if with the best of intentions), especially in light of new biology technologies. I wish that this book could be required reading for medical researchers & doctors in training.
