I came upon this unexpectedly, but what a timely find: Riding for the Team: Inspirational Stories of the USA's Medal-Winning Equestrians and Their Horses, edited by Nancy Jaffer. More than just the Olympic events, there are chapters on reining (the only Western event), driving, and vaulting. It was published recently enough, too, where you will recognize some of the names! Nice little biographies of how folks got started, who was a teacher, or mentor, or hero. Bits about their first horse (sometimes a Shetland pony), or their first great horse. A nice read given that I watched as much of the Equestrian Olympics as I could find. :-)
