Listened to the audiobook on a ten-hour drive, and it was so good, I could have kept driving just to hear the last two hours. This is nonfiction but it's so well crafted it reads like fiction. I found the science aspect fascinating and the social aspects heartbreaking. The book brings up the interesting question of whether one has the right to weigh in on how their removed tissues are used or whether the removed tissues become the 'property' of the doctors and hospitals that remove them. I read (listened to...) this both as a medical professional but also a daughter, which allowed me to consider it from both angles. I found it thoroughly engrossing.
