Don't confuse this guy with William Kunstler, the left wing lawyer from the 1960's.
Kunstler is a social scientist. He's abrasive, opinionated, condescending and hypocritical. He's also extemely intelligent, insightful, and a good writer. You have to hold your nose and take the medicine when you read him.
His first book, The Long Emergency explains his conception of modern life today, and why it can't be sustained. His work is a carefully researched, well thought out analysis of current trends in our society. Having looked at how things are going in the present, he makes an educated guess at what the future holds for us.
Kunstler is comparable to Jared Diamond, who wrote Collapse. Diamond is a frequent contributor to Science Channel, Discovery Channel, and National Geographic as well as the two History Channels. Diamond's book was made into a two hour History Channel production, which gives you some idea of the caliber of his work. Kunstler is right up there alongside him. Reading the Long Emergency will give substance to some of those vague concerns we all have. You'll find out that the "great pulsating brains" of the Ivy Halls have drawn some of the same conclusions you have about what's coming down the pike before very much longer.
After he wrote The Long Emergency, Kunstler went on to publish a fiction novel based on the first book. World Made By Hand has become a sort of cult classic, not only for the survivalist and prepper community but for a lot of the off shoots of those philosophies.
It follows the lives of some of the occupants of a small town after the collapse Kunstler believes is inevitable and coming soon. I thought he did a good job with his characters, and his plot line. It has some odd quirks you won't find in Shatter, The Pulse, Deep Winter or any of the other post apocalyptic fiction most of us have on the shelf, but that doesn't detract at all from the book.
When you read The Long Emergency you'll notice that the author is no fan of Southern Culture. He thinks Southerners are boorish, violent people with such low interests as, dare I say it, NASCAR. Yet in World Made By Hand, the two groups who prove the most resilient and practical are a migrating band of Southerners and veterans. The very traits that Kunstler looks down on from a philosophical aspect are what make these people so viable and important in the chaos of the collapse.
The Witch of Hebron is the sequel to World Made By Hand. It's a good book as well, and follows the same people through the traumatic and turbulent times that engulf their little town.
Overall, these three books will give you some insight into what may transpire in our immediate future. They're informative and entertaining. All three are available from Amazon as either print books or Kindle editions.
