The heyday of "war tourism" was probably the 1930s, when a host of intellectuals and artists left the U.S. to bear witness to the Spanish Civil War. Ernest Hemingway wrote about it. George Orwell, just to name another, actually fought in it.
"Every inch of that place, every grain of sand, wanted desperately to kill us."
That's a line from a compelling new novel about the Iraq War, written by former Marine Michael Pitre.
Pitre was a history and creative writing major at Louisiana State when he joined the Marines after Sept. 11. He became an officer and served two tours in Iraq's Anbar province working in logistics and communications.
