When Lisa Atwood and her mother visit friends in a nearby town, Lisa doesn't expect to have a good time. She doesn't seem to have a lot in common with Marguerite, the friend's daughter, so it could be a long afternoon. But when Marguerite suggests that she and Lisa go riding, things start to look up. Marguerite's horse is gorgeous, and she's very pleased with it. In fact, she's so pleased that she rides off and leaves Lisa on a strange trail. Lisa doesn't mind too much - her horse is old but sweet-natured and it's a nice day.
Then the mare stumbles, and Lisa is thrown. She can't ride and she can't walk. She's alone with just the horse for company. Can the horse care for Lisa and keep her safe until help arrives?
