The only thing that Robin Gibson wants for her sixteenth birthday is a 1968 Presidential Blue Mustang. Following their family tradition, what her parents promise her is a horse of her own, one with four legs, not four wheels. Mom competes in endurance riding, Dad does calf roping, her older brother games and her older sister loves three-day eventing, but Robin proudly says that she doesn't do horses. She'll teach her controlling family a lesson by bringing home the worst horse she can find, a starved, abused two-year-old named Twaziem.

Robin figures she'll nurse him back to health, sell him, and have the money for her car. Rescuing and rehabilitating the Morab gelding might be a bigger challenge than what she planned. He comes between her and her family. He upsets her friends when she looks after his needs first. Is he just an investment or is he part of her future? And if she lets him into her heart will she win or will she lose?
