Caring for a horse isn't always a picnic Erin is thrilled when her parents agree to buy her a horse. She doesn't even mind holding up her end of the agreement--keeping up her grades, mending clothes, and helping out with chores around the house. She'll do anything as long as it means having a horse of her very own. But owning a horse is nothing like Erin imagined. The old mare whom she names Spindrift can be grouchy and ill tempered. And having a horse means lots of extra responsibility--feeding her, grooming her, training her. Luckily, Erin's aunt Lexie knows a thing or two about horses and is willing to show her the ropes. But even Aunt Lexie can't keep Erin out of trouble entirely.
