STONE FACES is the story of a ten-year-old girl named Alice who notices one day that her parents' faces have turned to stone. Soon afterward, they tell her they are going to get divorced and, in reaction, she allows her own face to turn to stone because she doesn't want anyone to know how much this hurts her. It is easier to deal with her friends when her stone face is in place, but she also begins to find herself alone more and more. While on her summer vacation at her aunt's house on Cape Cod, she sees a stone on the beach in the shape of a laughing man's face (called Mr. Happy Man). She soon discovers that this stone can talk and that it has friends among the other beach stones, who play games in the sand when people aren't around. Together with Mr. Happy Man and his friends, Alice develops an ingenious scheme to help her parents resolve their differences. Their plans are thrown awry when a woman finds Mr. Happy Man in the sand and walks off with him. Alice decides to rescue the stone and sneaks into the woman's house where she learns that the woman is actually a witch.
