Shadow: The Curious Morgan Horse by Ellen F. Feld
Shadow is a young horse who is curious about everything. One day the farm’s rooster tells her about a magic pond in the woods and Shadow wants to go find it. When a tree falls during a storm and knocks the fence down, Shadow takes the chance to go explore the woods. She searches for the pond and along the way meets many different forest animals. But when Shadow realizes she has become lost, how will she find her way home?
