One Summer: America, 1927 is a 2013 history book by Bill Bryson. The book is a history of the summer of 1927 in the United States. It was published in October 2013 by Doubleday. The book focuses on various key events of that summer as lenses through which to view American life: what it had recently been and what it was becoming. Bryson does not address himself solely to American readers. For example, Babe Ruth and baseball are a major topic of the book, and Bryson gives useful explanations of this American game and its terminology.
