Patricia has always dreamed of learning to ride a horse. Finally, the summer she's ten years old, her father announces that the time has come. But when her father pulls up to a shabby stable run-down Dogpatch, Patricia's heart nearly breaks. How can her dreams possibly come true in a place like this? But Patricia is in for a big surprise; for here in Dogpatch she meets two wonderful individuals; kind, patient Mrs. Mack and a glorious chestnut mare named Penny-who will change her life forever.
