i dont read a ton of non-fiction, but i've been reading alot lately. Im currently reading The Road by Cormac McCarthy, and its living up to the hype from the person who recommended it. Probly read 20ish books in the last year, some of which are:

The Kite Runner and A thousand Splendid Suns by Khaled Housseini
Tuesdays with Morrie, The Five People You Meet In Heaven, and For One More Day all by Mitch Albom
Freakonomics
Body of Lies by David Ignatius
Farenheit 451 by Ray Bradbury
Sacred by Dennis Lehane - This is the guy who wrote Mystic River and Gone Baby Gone, both excellent movies.
The Associate and The Appeal by John Grisham - all Grisham books are goot
Breakfast of Champions and Slaughterhouse Five by Kurt Vonnegut
Ishmael by Daniel Quinn

Sounds like you're looking for more non-fiction, but if you feel the itch any of these books are a good read. Up next is Blood Meridian also by Cormac McCarthy and The Night Gardener by George Pelecanos (lead writer for The Wire)
