This book chronicles the history of the Philadelphia Athletics, the first real dynasty in Major League Baseball. The focus of the book is the 1931 season, where Philadelphia, led by is superstar pitcher, Lefty Grove, had the best season in franchise history, leading to a third consecutive trip to the World Series.

With a roster full of future Hall of Fame players like Al Simmons, Mickey Cochrane, Jimmie Foxx, Connie Mack, and Lefty Grove, the Athletics were one of the best baseball teams of all time, and the 1931 season served as the apex of their success, as the financial restrictions of the Great Depression caused team ownership to break up the team.
