This book makes the jump from 5 stars (generally I don’t bother to review a book if it is not a four or five star read) to 6 stars — my top ten percent — because of the combination of Questions Asked, glorious color graphics, and the total holistic nature of the book — this is easily a PhD thesis in holistic analytics, true cost economics, and open source everything engineering. Indeed, this book could be used as a first-year reference across any humanities and science domain, they would be the better for it.

6-Star Guide to Saving Every City in Every Country — a World-Changing Book
This is an extraordinary book, easily five stars but I am elevating it to 6 stars (my top ten percent across over 2000 reviews, all but a handful non-fiction) because the author is not just a genius, but he explains his deep multi-level knowledge brilliantly. I have never seen a collection of complicated nuanced topics presented in such a compelling, easy to understand, well-illustrated manner. The case studies abound. The publisher is to be complemented for the purity of the presentation — a stunning book with perfectly laid out pages, glossy color on every page, and a superb index, which is where most publishers fail their authors.
