Elfie Oster was sure that Hampshire Academy was going to be the perfect school for her. She was sure about it right up to the minute she got expelled. On her first day.

It was all a terrible misunderstanding, but until she can find a way to fix things, Elfie has to go back to Cottonwood Elementary for fifth grade. Where she's never really fit in. Or had friends. It is not a perfect situation. And then it gets worse. Her babysitter gets really sick. Her aunt and uncle aren't speaking. She's forced to do a group project involving an egg. . . .

But sometimes when everything goes spectacularly wrong, you figure out what truly matters--and what doesn't. So really, this terrible, horrible, surprisingly hilarious year may just be the best thing that's ever happened to Elfie.
