Children’s book about a brother and sister who discover where their father’s lost socks go. In Socksville, his red socks and white socks go to baseball games, his polka-dot sock sings, his gym socks run in relay races and the children’s socks play at the park. Tomas and Matilda convince their socks to come back home if they can do all of the fun things they do in Socksville. The socks do come back home and “train” their Dad to have more fun, by hiking, dancing, singing and going to baseball games. Dad is happier and so are the socks, at least for now.
