Fiona lands herself in a fairground fluster in this conclusion to the mischievous and charming Not-So-Ordinary Girl trilogy. Fiona is tired of hearing “no” from everyone. Especially when it is followed “You’re not old enough.” Can she go all the way to California by herself to visit her mom? “Not on your life,” says Dad. Can she do something more exciting than handing out maps at the Great Ordinary Fair along with the rest of Mr. Bland’s class? “Not until next year, when you’re in fifth grade,” answers Mr. Bland. Fiona sets out to prove that she is, in fact, old enough to do things on her own—and ends up babysitting chickens in the fair’s poultry pavilion. It’s not easy being trustworthy and mature, especially when nobody is paying attention. But when the feathers start to fly at the Great Ordinary Fair, Fiona sticks her neck out for a new friend (and a bunch of chickens) and learns a few things about herself and what it means to take responsibility, even when things go really wrong.
