This is a truly remarkable human story, which is why it gets four stars despite a couple of significant issues. Many non-fiction literary agents have a mantra of 'Is it an article?' for a book proposal that really hasn't got enough content to justify a full length manuscript.

The other problem I had was that I was sold this title as popular science - if the book had included science content it could have been far more engaging, but the author clearly has no interest in science or maths and skims over any technical issues as quickly as possible - what remains is pure social history. Despite that disappointment I can only say in awe again, what a story!
