In May 2002, Arizona Cardinals safety Pat Tillman, deeply troubled by the events of 9/11, walked away from a $3.6 million NFL contract to enlist in the United States Army. Two years later, he was killed by friendly fire on a hillside in southeastern Afghanistan. Bestselling author Jon Krakauer (Into Thin Air, 1997 and Under the Banner of Heaven, 2003) draws on Tillman’s journals and letters, interviews with family, friends, and fellow soldiers, and his own research in Afghanistan to write this compelling biography of a true American patriot.
