Thoroughly enjoyed this book. It provides terrific insight to the lives and thought processes of leading scientists in the field of particle physics. It's a real page turner that does a great job of communicating what drives these people and the hurdles they come up against. I envy Ian Sample's experiences in meeting and picking the brains of the scientists and admire his perseverance in digging into the detailed and tough topics.
I would agree with other reviewers that it felt thin on science from time to time but maybe that's a good thing. By the end of the book I think that I understand a bit more about the physics discussed but I'm still struggling, and I'm a scientists! Too much detail and I might have turned off.
Overall, very readable and enjoyable.
