Poise, class, confidence, fantastic thighs and an even better ass: these are the spoils of an equestrian lifestyle. And Margaret Fletcher has them all. But then suddenly, she doesn't. Broke and horseless for the first time in her pampered life, Margaret is lost in a sea of tangled hairnets until a cranky old horseman introduces her to the not-so-glamorous world of exercising young racehorses. Margaret knows she can jump a five foot fence with style. But can she gallop forty miles an hour on a two-year-old rocket launcher with sticky brakes? Enter Emily Morris, a working class eventer who’s spent her whole life eating the dust of rich girls like Margaret. Now, charged with the task of turning this clueless Hunter Princess into a fully-functional Gallop Girl, Emily will have to teach her the basics of horsemanship from the ground up ― mud, manure and all. Can a former Hunter Princess and a scrappy kid from the wrong side of the racetrack team up to conquer the “Sport of Kings?”
