I don't read a lot of non-fiction, but books by Jon Krakauer are an exception. That's because Krakauer is an expert on making true stories read like a novel. Like many of Krakauer's books, I could hardly put down Into the Wild http://www.amazon.com/Into-Wild-Jon-Krakauer/dp/0385486804
I am not a mountaineer, but I was fascinated by Krakauer's account of Chris McCandless, a well-educated young man who walked into the wilderness near Mt. McKinley and never returned. McCandless viewed himself as a modern day aesthetic, eschewing all worldly possessions as he set out to live off the land http://www.christophermccandless.info
Sadly, McCandless did not survive his ordeal in the harsh Alaska wilderness, likely dying of starvation. Apparently, McCandless was hoping to find himself by loosing himself in nature. Krakauer did a magnificent job of chronicling the McCandless's misadventures. Using writings left behind in the abandoned bus McCandless called home plus interviews from his family, Krakauer weaves a narrative which is exciting and interesting, even knowing the outcome beforehand.
I applaud Krakauer for his work as a writer and would recommend his books to anyone in need of a good, but true story http://www.jonkrakauer.com/books
I have awarded Into the Wild 4 out of 5 stars on my Goodreads Page
