From Amazon's description:
Equal parts droll and gorgeous nostalgia book and heartfelt plea for a renewed sense of adventure in the lives of boys and men, Conn and Hal Iggulden's The Dangerous Book for Boys became a mammoth bestseller in the United Kingdom in 2006. Adapted, in moderation, for American customs in this edition (cricket is gone, rugby remains; conkers are out, Navajo Code Talkers in), The Dangerous Book is a guide book for dads as well as their sons, as a reminder of lore and technique that have not yet been completely lost to the digital age. Recall the adventures of Scott of the Antarctic and the Battle of the Somme, relearn how to palm a coin, tan a skin, and, most charmingly, wrap a package in brown paper and string. The book's ambitions are both modest and winningly optimistic: you get the sense that by learning how to place a splint or write in invisible ink, a boy might be prepared for anything, even girls (which warrant a small but wise chapter of their own).
And then from their interview with one of the co-authors:
Amazon.com: It's difficult to describe what a phenomenon The Dangerous Book for Boys was in the UK last year. When I would check the bestseller list on our sister site, Amazon.co.uk, there would be, along with your book, which spent much of the year at the top of the list, a half-dozen apparent knockoff books of similar boy knowledge. Clearly, you tapped into something big. What do you think it was?Iggulden: In a word, fathers. I am one myself and I think we've become aware that the whole "health and safety" overprotective culture isn't doing our sons any favors. Boys need to learn about risk. They need to fall off things occasionally, or--and this is the important bit--they'll take worse risks on their own. If we do away with challenging playgrounds and cancel school trips for fear of being sued, we don't end up with safer boys--we end up with them walking on train tracks. In the long run, it's not safe at all to keep our boys in the house with a Playstation. It's not good for their health or their safety.
You only have to push a boy on a swing to see how much enjoys the thrill of danger. It's hard-wired. Remove any opportunity to test his courage and they'll find ways to test themselves that will be seriously dangerous for everyone around them. I think of it like playing the lottery--someone has to say "Look, you won't win--and your children won't be hurt. Relax. It won't be you."
I think that's the core of the book's success. It isn't just a collection of things to do. The heroic stories alone are something we haven't had for too long. It isn't about climbing Everest, but it is an attitude, a philosophy for fathers and sons. Our institutions are too wrapped up in terror over being sued--so we have to do things with them ourselves. This book isn't a bad place to start.
As for knockoff books--great. They'll give my son something to read that doesn't involve him learning a dull moral lesson of some kind--just enjoying an adventure or learning skills and crafts so that he has a feeling of competence and confidence--just as we have.
