There are myriads of Particle Physics books and they tend to drown you in maths from page 1. I have quite a few on my shelf, being an engineer with an interest in the matter and going beyond the popular science stuff. This book is different, much softer and down to earth in showing only the basic maths and giving lots of background, history, and physical insight to explain the equations and the results. It is a "post Higgs discovery" book, and it explains the story quite well, I thought. I would recommend this warmly if you want to go beyond basics, but not too far. I enjoyed the book.
