Emmy Addison is an ordinary girl—almost. If you don’t count the fact that her parents are rich (very), her best friend is a boy (and a soccer star), and she can talk to rodents (and they talk back), she’s very ordinary indeed. But she hasn’t been that way for long . . .
It was only a few weeks ago that Emmy and her friends Ratty and Joe got rid of the evil Miss Barmy, the nanny who had nearly ruined Emmy’s life—and the lives of five other girls who went missing. Miss Barmy is now a rat. How much harm can she do?
