The summer of 1899 is hot in Calpurnia's sleepy Texas town, and there aren't a lot of good ways to stay cool. Her mother has a new wind machine, but instead, Callie's contemplating cutting off her hair, one sneaky inch at a time. She's also spending a lot of time at the river with her notoriously cantankerous grandfather, an avid naturalist. But just when Callie and her grandfather are about to make an amazing discovery, the reality of Callie's situation catches up with her. She's a girl at the turn of the century, expected to cook and clean and sew. What a waste of time! Will Callie ever find a way to take control of her own destiny?
