Twelve-year-old Sky and her father are horse whisperers--their preternatural tenderness and understanding of horses, and Sky's uncanny ability to actually understand what they're saying, become their livelihood during the foaling season at multimillion dollar horse farms. They're sought after by the most prestigious farms in the country to keep pregnant horses calm and stress-free until they give birth. But this spring, something awful is happening...foal after foal is a stillborn, and no one knows why. And worse for Sky, who lost her mother only months earlier, her most beloved horse is about to have her first foal. In agony, Sky takes it upon herself to figure out what the vets are missing, and stop it before even more foals are lost.
