Stevie has always longed for a horse of her own, and this summer she finally has the chance to get one. When she and the rest of The Saddle Club head West to the Bar None Ranch to visit their friend Kate Devine, Kate's dad agrees to sell Stewball, Stevie's favourite ranch horse. But as the day to bring Stewball back home draws nearer, Stevie begins to have second thoughts. Does a ranch horse really belong at Pine Hollow Stables?
