When Nan Mooney was seven years old, she sat in her grandmother May-May's living room to watch her first horse race ... And so began a turbulent romance between a woman and a sport.

Part memoir, part journey into the compelling world of Thoroughbred horse racing, My Racing Heart gallops headlong into the wild culture and fabulous creatures that rise up around a racetrack. Nan Mooney looks at the horses, jockeys, and trainers; the gambling and corruption; and racing's age-old history and forever offbeat society. From the dusty backstretch at a small-town track to the stands at magnificent Churchill Downs, Nan Mooney captures the risks and the glory, the excitement and the passion, for horse lovers, sports fans, and anyone who has ever craved a place to run wild.

Nan Mooney grew up in Seattle, half an hour north of Longacres racetrack, and graduated from Scripps College in California. Her work appears in The Blood-Horse, the journal of record for Thoroughbred horse racing. She lives in New York City. You can reach her at myracingheart.com.
