Season of '42: Joe D., Teddy Ballgame, and Baseball's Fight to Survive a Turbulent First Year of War by Jack Cavanaugh

Description from Goodreads: "Big league baseball would seem to have been a hard sell in 1942. World War II was not going well for the United States. Moreover, Uncle Sam needed men, millions of them, including those from twenty-one through thirty-five years of age who had been ordered to register for the draft, the age range of most big league baseball players. The 1942 season would be overshadowed by war, though, with many people wondering whether it was really all right for four hundred seemingly healthy and athletic men to play a child’s game and earn far more money than the thousands of young Americans whose lives were at risk as they fought the Germans and Japanese abroad."

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."
