Pat Tillman's death by friendly fire was covered up just days before his comrade Rory Fanning--who served in the same unit as Tillman--left the Army Rangers as a conscientious objector. Disquieted by his tours in Afghanistan, Fanning sets out to honor Tillman's legacy by crossing the United States on foot. Told with page-turning style, humor, and warmth, Worth Fighting For explores the emotional and social consequences of rejecting the mission of one of the most elite fighting forces in the world. It is only through the generous, and colorful people Fanning meets and the history he discovers that he learns to live again.
