Jon Krakauer draws on Tillman's journals and letters, interviews with his wife and friends, conversations with the soldiers who served alongside him, and extensive research on the ground in Afghanistan to render an intricate mosaic of this driven, complex, and uncommonly compelling figure as well as the definitive account of the events and actions that led to his death. Before he enlisted in the army, Tillman was familiar to sports aficionados as an undersized, overachieving Arizona Cardinals safety whose virtuosity in the defensive backfield was spellbinding. With his shoulder-length hair, outspoken views, and boundless intellectual curiosity, Tillman was considered a maverick. America was fascinated when he traded the bright lights and riches of the NFL for boot camp and a buzz cut. Sent first to Iraq--a war he would openly declare was "illegal as hell" --and eventually to Afghanistan, Tillman was driven by complicated, emotionally charged, sometimes contradictory notions of duty, honor, justice, patriotism, and masculine pride, and he was determined to serve his entire three-year commitment. But on April 22, 2004, his life would end in a barrage of bullets fired by his fellow soldiers.
