I didn't get around to writing this review right after I finish the book, as I usually do. I won't be as detailed as I like with this review because of this. I do however remember very distinctly that I flew through this book and was very surprised since some chapters were dense with the science of HeLa. I read one of those chapters to my boyfriend who stated "how can you read that!" I loved every bit. Many reviewers have complained that there isn't enough science background to the cells in the book but I think they missed the point of the book (which is clearly defined in the pages by the Lacks Family.) I won't go into too much detail here but the important parts of the book are the STORY and this is what makes this book so wonderful. I thought it had the perfect balance of science with a side of humanity that made me want to devour every page. I would recommend this book to anyone!
