Lots of reviews on this but I don't elaborate on my reviews I make them short and sweet. So don't read this book if you aren't interested in the biological story and ethical issues behind HeLa cells. Henrietta is only prominent in the first part of the book (can't say chapters because I was listening to audio book). The remainder of the book is the struggle of her daughter (who never knew her mother because she was too young) to come to terms with the scientific uses of her mother's cells. In addition there is a lot on the ethical issues of using people's cells/tissues without there knowledge. My undergraduate degree is in biology so I learned a lot in the book and found it quite interesting. If science isn't your thing you may find it tedious.
