"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-sitter's Club is starting a new play group. It's going to be so much fun! But then Mimi has a stroke, and the whole summer changes. Now Claudia is 'Mimi-sitting, ' and Janine is no help at all. How can the Kishi sisters get along when Janine is always so mean?"--Provided by publisher.
