I've heard of this...don't think i've read the book yet. I read Jon Krakauer, 'Everest' and 'Into the wild'.
The first one being about the everest disaster of the nineties, something like 25 people went up there, and i think four of them died or something.
Into the Wild was about a young man who decided it would be a good idea to walk into alaska with nothing but a pair of boots and a rucksack!!
