Exactly as described in the subtitle: excellent, powerful, and persuasive.
Back in 2010 I made a decision which baffled many of my friends and coworkers. I essentially quit my job (technically I took a leave of absence, but I knew I wasn't going back), packed or sold all my things, caught a train, then walked out into the woods. I spent from September to December living alone out on a wooded coastline, fishing, gathering, and building a shelter to live in. The following year, I went back and did it again.
This is the book I wish I had had at the time.
It is a comprehensive, well-written, superbly researched and powerful arguement for taking the time to live out in nature for an extended period. As the author has done, on more than one occasion.
The author covers all manner of the many facets of an extended wilderness adventure, many often lacking in other books. Admirably, he also makes it clear that it is impossible to fit everything needed into a single book, but lists an extensive and wonderful bibliography, which reads somewhat like my bookshelves. The other appendices are likewise an exceptional bonus to the text itself.
Finally, it is important to mention the angle the author approaches this vast topic - from one of living as a PART of nature, not man vs nature, from one of being a student of the environment and ecological world around us, not as a man in a bubble, out in the woods. This is crucial - the study of our ancestral skills is one of our place in the natural world - for those of us who have taken time out from what others call civilisation, this is what it is all about. Knowing we are a part of the world and moving with it in as close to a harmony as possible.
In short, if you even have a tiny bit of interest in this topic, do buy this book. You will not be disappointed. And if you aren't interested, then this book might well be the one to convert you.
A powerful, engaging, superbly researched (and experienced) read. Buy it.
