I love travel books, the more extreme the better, so anything by Redmond O'Hanlon is usually a great read. He's a crazy guy from Oxford who visits the most hostile natural places on earth and tries to explore like someone back in the 1800's used to. Congo Journey is a good example, and worth buying.
John King writes some good stuff too, though it's usually a very "English" read. I just finished "White Trash" by him, and it's on par with the others "Football Factory", etc.
If you want to be put off sex for life, try anything by Peter Sotos. He writes about sex exclusively, but seems to hate it with a deep passion. He's almost a DeSade for the modern age. Brutal stuff.
