Book excerpt: For a young science whiz, an eagerly awaited day at the Fair turns into a wacky adventure with more twists and loops than the Gravity Whirl ride! Miller Sanford's parents think he's too young to explore the annual town fair alone. Hopeful that they will reconsider this year, Miller works extra hard to be nice to his little sister Penny and her friends. But when his mother can't attend the Fair and his father has to cover her volunteer booth hours as well as his own, Miller ends up with more responsibility than he can handle. Instead of enjoying a freewheeling day on his own, he is drawn into a series of mishaps involving everything from his dad's prize-worthy lemon meringue pie and his own ill-fated science fair project. Frank Dormer's kid-friendly illustrations enliven the pages of Leslie Bulion's lighthearted take on growing up and learning to be responsible.
