Between showing the award-winning jumper Mirror Glider, working at South Hills Stables, and washing dishes in her dad's South Asian family restaurant, thirteen-year-old Dev Rani doesn't always have a lot of time left for homework or a social life. But when Mirror Glider has an accident and is forced to retire, Dev is suddenly faced with a new problem: Zim, a promising, but very disturbed, rescue horse. Dev is charged with convincing this troubled Arabian to become the jumper she knows he can be. But first, she needs to learn more about this abandoned horse's history -- and things get more complicated than she bargained for.
