Tim Hetherington was a photojournalist who died in 2011 while covering an uprising against Muammar Gaddafi in Libya. His book Infidel is a poignant photographic look at a small battalion of US soldiers stationed in the Korengal Valley of Afghanistan. Tim Hetherington was a well-respected photographer because he used his lens to reveal the humanity of his subjects as well as the historical significance of the moment. The pictures are allowed to speak for themselves since they are the only thing you see until the back of the book, where there is commentary describing each picture. In addition, some of the soldiers write about their experiences themselves. The introduction is written by Sebastian Junger, the author of The Perfect Storm and War, among other books. Junger worked with Tim Hetherington on the documentary Restrepo , which looks at the same outpost in the Korengal Valley. Restrepo was the winner of the 2010 Sundance Best Documentary.
