At the riding school, much to Angel's sorrow, Sparkle was sold to another girl... and Angel is never allowed to touch him again. But Sparkle neighs every time he sees her. How is she supposed to keep that up? Fortunately, Angel gets to do a lot with Saffraan, the new riding school pony. He really is a sweetheart, but driving is not going well at all. Can Angel help him? Angel's search for her father finally has a result, because her mother has an appointment with him soon. Angel is no longer nervous. Will her father want to meet her?
