One hundred years ago, in September 1918, three things came to Boston: war, plague, and the World Series. This is the unimaginable story of that late summer month, in which a division of Massachusetts militia volunteers led the first unified American fighting force into battle in France, turning the tide of World War I. Meanwhile the world's deadliest pandemic--the Spanish Flu--erupted in Boston and its suburbs, bringing death on a terrifying scale first to military facilities and then to the civilian population. At precisely the same time, in a baseball season cut short on the homefront and amidst the surrounding ravages of death, a young pitcher named Babe Ruth rallied the sport's most dominant team, the Boston Red Sox, to a World Series victory--the last World Series victory the Sox would see for eighty-six years.
