Stacey's parents are getting a divorce. Stacey is sad and angry, and she has a big decision to make - stay in New York with her father, or move back to Stoneybrook with her mother....

Lately, it seems like each of the baby-sitters besides Dawn has been singled out...and she's a little jealous. But now it's Dawn's turn to shine: Mrs. Pike has asked her to help prepare Margo and Claire for the Little Miss Stoneybrook contest....

Lately, the pressure's really been on Stacey. She hasn't been feeling well, her schoolwork and baby-sitting jobs are almost out of control, and she's sick of being in the middle of her parents' fights....

Stacey's so excited! She's invited her friends in the Baby-Sitters Club to New York City for a long weekend. It's going to be perfect - a party and a sleepover on Friday, a big baby-sitting job on Saturday, and lot of sightseeing on Sunday. But what a mistake....

After Kristy's mom got married, her family moved to a new neighborhood. But the kids there aren't very friendly - in fact, they're total snobs! They criticize Kristy's clothes, make fun of the Baby-Sitters Club, and they laugh at Louie, Kristy's pet collie, who's going blind....
