Winnie Finn loves worms and knows everything about them. At this year's county fair, Winnie would like nothing better than to win the grand prize, a wagon to transport her worms around. The trouble is, there is no prize for raising worms. Exercising her creativity, however, Winnie uses her worms to help solve some of the town people's problems, and to win her prized wagon. At the back of the book, the author provides information on worms and composting.
