Miranda Stevens decides being a teenager and in junior high school is complicated. Her best friend's seventeen-year-old cousin comes to live with Laurie—and to break up her friendship with Miranda. A new boy in school wants all of Miranda's attention when she would rather be riding horses with Christopher. But Chris is spending his time with Jody, the new girl in their class.

Miranda much prefers the world of horses. But that gets complicated, too, when she is only half-owner—and not the controlling half—of Starlight, the fastest race horse in the country. She can't keep Mr. Taylor from taking him to races, but when he takes Starlight to a sale, along with his other top racing stock, Miranda feels completely betrayed. If he sells Starlight, she will never forgive him. When Mr. Taylor returns, however, he is as surprised and baffled by Starlight's disappearance as she is. All they can think is that someone has stolen him and that their chances of finding him are not good.

In this book about an expanding family of people and horses. It chronicles birth and death, friendships lost and won, heartache and triumph as Miranda's—and Starlight's—loyalty and devotion to friends and to each other are tested.
