"Claudia's sister, Janine, is too busy being smart to be nice to anyone-- even their grandmother, Mimi. But Claudia doesn't have to see Janine too much this summer since the Baby-sitters Club is starting a new play group. It's going to be so much fun!

How can the Kishi sisters get along when Janine is always so mean?"--Page 4 of cover.
