Book excerpt: In the irresistible sequel to Emmy and the Incredible Shrinking Rat, Emmy, Joe, and Ratty rescue other children Miss Barmy has preyed upon 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?
