Poppy is so excited. Her best friend Sarah is finally coming to visit Starlight Stables. She is sure that Sarah will love it all as much as she does -- especially Poppy's beautiful pony, Crystal, and her horse-mad friends, fiery Milly and sweet Katie. But it soon becomes clear that Sarah doesn't share Poppy's love of horses and riding -- in fact, she's more interested in helping Poppy's uncle with some injured animals. When a bushfire erupts nearby, Poppy finds herself fighting not only to save her friendship but also to save her beloved Starlight Stables. Will she lose everything she loves?
