I picked up this book hoping it would tell me more about the HeLa cells and the background to them. It sort of does that, except it's really more a book about how the author gathered the information in the book - "I went here, met X, went somewhere else, met Y". As a result, it ends up feeling like the author has inserted herself into the story, and perhaps also got a bit too close to the participants.

For me, this is one of those books which isn't that fulfilling on its own, but a good jumping off point by following up the references etc.
