Cesco and the Mushrooms by Philip M. Bonello

Little Cesco loves running errands for all the people in his village, and everybody loves him for it. One day, old Carrie who lives at the edge of the village asks him to pick some wild garlic for her. Cesco must venture into the dark woods for this errand … but what happens when he finds he has walked too far? How shall he ever find his way back home? It may be dark under those gloomy oaks but how else is Cesco to see the magic of the woods?
