It's fun to be a Baby-sitters' Little Sister!
For New Year's Eve, Karen thinks everyone should make a promise. Hannie is going to stop biting her nails. Kristy promises not to talk to her boyfriend on the phone so much. And Karen makes the most promises of all ? nine!
But pretty soon, everyone starts breaking their promises. And her brothers and sisters are calling Karen a spy!
Poor Karen. Why is everyone being bad except her?
