Wow, this was an awesome book! It discusses the life of Henrietta Lacks, the donor of the tumor that was used to develop the immortalized cell line HeLa. The narrative alternates between the story of Henrietta’s family and a scientific discussion of the HeLa’s huge contribution to modern medicine. This is by far the most human story of science/medicine I’ve ever read. Everyone should read it! Additionally, the audiobook won the Audie Award because of its excellent performance. 5/5 stars.
