Against the backdrop of the high-moneyed and sometimes unscrupulous equestrian sport of show jumping, fifteen-year-old Finny adopts an emaciated, untrained horse without her parents’ knowledge.

Soon after adopting Sky, Finny meets Joe, a sixteen-year-old, who has run away from his cruel uncle in Montana. His love for horses and desire to be a trainer match Finny’s dream of competing in the show jumping arena—against rich girls on fancier horses—and together, they train Sky to become a first-rate show jumper.

But the path is fraught with danger when Joe is kidnapped by his violent uncle, Finny and Sky are the only ones who can save him.

In a breathtaking finale, Sky and Finny must enter the underworld of the rodeo circuit, an after-hours, illegal race, where they will risk their lives to save the boy they love.
