An absolutely fascinating book. Henrietta Lacks was diagnosed with cervical cancer in the 1950's. She didn't survive treatment, but cells taken from her tumors are still being cultured and used in experiments today. This book is the story of how the Lacks family learned of Henrietta's "immortality" and the dialogues on bioethics the treatment of the Lacks family (and others) sparked. Skloot makes the science understandable and really stresses the human side of the story. Highly recommended.
