"Infidel" presents a deeply personal view of a U.S. platoon in the Korengal Valley, Afghanistan, one of the war's most perilous postings. Photographer Tim Hetherington, embedded with writer Sebastian Junger, captures a year's worth of images highlighting the soldiers’ camaraderie, vulnerability, and resilience. The book includes intimate interviews and graphics of soldier tattoos symbolizing their bond. An introduction by Junger complements insights revealed in their co-directed film, "Restrepo." Hetherington, an acclaimed British photojournalist from Liverpool, has received numerous awards and is a Vanity Fair contributor. His work provides a tender yet stark war documentation.
