This book is an extremely well organized presentation of key theories and evidence in behavioral game theory, a subset of topics from the field of behavioral economics. I have often assigned chapters 1 and 2 in behavioral economics classes at Harvard and Duke, and recommended other chapters to students who want to learn about Learning theory. (I would cheerfully assign the other chapters if I happened to be covering those topics, but there's only so much you can squeeze into a 1-semester undergraduate course!)
The book has many strengths. First, Camerer is one of the Very Important Scholars in behavioral economics, and there are less than a handful of people (Matt Rabin) who could conceivably be argued to be more authoritative on the subject matter. Second, Camerer makes extraordinarily good use of summary tables, explicit sections/subsections/subsubsections, summary paragraphs, and the like to help the reader keep track of the details, and to quickly locate the particular details of interest. Third, the introductory chapter offers a wonderful and intuitive introduction to the field; I have often started the first class of a new semester by reproducing the experiments in the chapter as classroom demonstrations. Fourth, the appendices to the introduction offer a good overview of economics experiments and of game theory (no substitute for a full textbook on game theory, of course, but a good refresher, and enough to get the bare bones of the subject). I expect the reader will quickly find many other reasons to admire this book.
This is NOT a book for a casual read by a non-economist. It's a textbook, or a handbook for economists and other people with a reasonable mathematical background who want to see, in one place, the most important results in behavioral game theory (as of a few years ago). It's also designed to present scholarly research, which means the reader should be prepared for the scholar's willingness to leave a lot of loose ends lying around and NOT to claim to know the definitive answers to the questions.
If you are a lay person looking for a behavioral economics book for the general audience, you should probably look to Richard Thaler and Cass Sunstein's Nudge or Dan Ariely's Predictably Irrational. All three of those authors are first-tier scholars and major contributors to the literature in their own right, and those books are written with a non-specialist audience in mind.
