Best Books discussion

Can someone recommend a good (or your favorite) non fiction book?

All the books are fiction books... or not?. Héctor

One of the best: Critique of Cynical Reason by Peter Sloterdijk. Published by University of Minnesota Press (January 1988)

my favorite nonfiction book: A Brief History of Time by Stephen Hawking

other good ones: Orientalism by Edward Said, People's History of the United States by Howard Zinn and Freakonomics by Stephen Levitt

A Short History of Nearly Everything by Bill Bryson is amazing. I've read it twice, and then I got the illustrated version! Is there a particular area in non fiction that interests you?

thanks for all the replies. A Short History sounds intersting... my favorite question is "Why". That's why I liked the tipping point and freakonomics

Random Family, by Adrien LeBlanc. Fascinating.

A couple of my favs have already been mentioned but Simon Winchester (Krakatoa esp.) and Dava Sobel (Galileo's daughter) rate high on the list. Bill Bryson's 'English Language the mother tongue' is a great read as is his 'small history'.
