A competitive bug is sweeping through Whitebrook Farm. Image, Star, and Gratis are all contenders for the Triple Crown races, which begins with the Kentucky Derby, a little over a month away.

Christina can't stand the pressure. So, when she is given the chance to leave Kentucky for a little while and ride for another farm in California, where Derby fever isn't quite as intense, she packs her bags and takes Star with her. There, Chris focuses on making the most of Star's running style. He's always been a come-from behind-horse, but he sometimes misses his chance to beat the leaders. Christina is going to try to change that in time for the Derby. But it may not be as easy as she thinks.
