Lily and Trooper's Fall

In this third book of the series, Lily and Trooper discover the wonders of fall. As they wake up they see leaves fluttering by the window and realize that autumn pleasures await. First they jump in a pile of leaves. When it begins to rain, they turn an umbrella into a sailboat. Later they fly a kite and crash their wagon into a leaf pile. That night they fall asleep reading a story about a girl and her dog.
