The Men Who Stare at Goats (pb) by Jon Ronson for 4 dollars.
Terror and Consent: The Wars for the Twenty-First Century (hc) by Philip Bobbitt for 2 dollars.
Turkmeniscam: How Washington Lobbyists Fought to Flack for a Stalinist Dictatorship (hc) by Ken Silverstein for 2 dollars.
Free Lunch: How the Wealthiest Americans Enrich Themselves at Government Expense (And Stick You with the Bill) (pb) by David Cay Johnston for 1 dollar.
The Gamble: General David Petraeus and the American Military Adventure in Iraq, 2006-2008 (hc) by Thomas Ricks for 6 dollars.
Of these, the only one I've read before is Free Lunch. However, I've been interested in reading The Gamble since watching Ricks lecture on the book.
Regarding Philip Bobbitt, I am not all that sympathetic to what I perceive to be his views on the national surveillance state, but have found myself desperate to find some intellectually challenging views that are not deranged after years of listening to AM radio and watching Fox News.
