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 from town, but Callie might just have to resort to stealthily cutting off her hair, one sneaky inch at a time. She also spends a lot of time at the river with her toriously cantankerous grandfather, an avid naturalist. It turns out that every drop of river water is teeming with life all you have to do is look through a microscope! As Callie explores the natural world around her, she develops a close relationship with her grandfather, navigates the dangers of living with six brothers, and learns just what it means to be a girl at the turn of the century. Debut author Jacqueline Kelly deftly brings Callie and her family to life, capturing an unusual year with unique sensitivity and wit.
