A Bit of Non-fiction
You have probably seen the Sean Penn film (or at least heard of it) Into the Wild. That is based on Krakauer's book of the same name, which tells the biographical story of Christopher McCandless in Alaska. It's a fascinating read. Then there is Into Thin Air, which is about the catastrophic 1996 Mount Everest expedition, at which Krakauer was present - another good read. However, if tales of extreme physical ordeal are not your sort of thing, you could try Under the Banner of Heaven: A Story of Violent Faith instead. It is about Latter Day Saints / Mormons and murder - probably a much better read than my brief summary would indicate. I haven't read it but it looks interesting so I'd be interested in any opinions you'd like to pass on.
