The Stranger in the Woods: The Extraordinary Story of the Last True Hermit by Michael Finkel

Trade paperback format. 

Recommended!  The story of Maine's notorious North Pond Hermit.  Strangely immersive and fascinating, a consideration of one man and how human's choose to relate to their world.

A National Geographic Best Book of the Year

Many people dream of escaping modern life. Most will never act on it—but in 1986, twenty-year-old Christopher Knight did just that when he left his home in Massachusetts, drove to Maine, and disappeared into the woods. He would not have a conversation with another person for the next twenty-seven years.
 
Drawing on extensive interviews with Knight himself, journalist Michael Finkel shows how Knight lived in a tent in a secluded encampment, developing ingenious ways to store provisions and stave off frostbite during the winters. A former alarm technician, he stealthily broke into nearby cottages for food, books, and supplies, taking only what he needed but sowing unease in a community plagued by his mysterious burglaries.

Since returning to the world, he has faced unique challenges—and compelled us to reexamine our assumptions about what makes a good life. By turns riveting and thought-provoking, The Stranger in the Woods gives us a deeply moving portrait of a man determined to live his own way.
