American Sniper by Chris Kyle with Scott McEwan and Jim DeFelice
Description from Goodreads: "From 1999 to 2009, U.S. Navy SEAL Chris Kyle recorded the most career sniper kills in United States military history. Iraqi insurgents feared Kyle so much they named him al-Shaitan (“the devil”) and placed a bounty on his head. Gripping and unforgettable, Kyle’s masterful account of his extraordinary battlefield experiences ranks as one of the great war memoirs of all time. Kyle talks honestly about the pain of war and in moving first-person accounts throughout, Kyle’s wife, Taya, speaks openly about the strains of war on their family."
