Stacey's vacation is full of mishaps when she tells one little lie which leads to another and another and another. 

Deciding that she wants to move back to California permanently, Dawn worries about what she will say to the rest of the baby-sitters, who do not understand when they hear the news secondhand.

Claudia's not worried when she hears her newest baby-sitting charge, Betsy, is a great practical joker. After all, how much harm can one girl do? As it turns out - plenty! Claudia breaks her leg because of one of Betsy's mean jokes...and now she's talking about quitting the club. Baby-sitting might be too dangerous. The rest of the BSC decides that Betsy needs to be taught a lesson - and the joke war is on!

Claudia's loving the October weather and her many friends, both in school and in the BSC. But when she throws a party to bring her two groups of pals together, she creates more problems than she solves.

Hired as the temporary companion to young Victoria Kent, who is distantly in line for the British throne, Mary Anne has trouble getting the girl to open up to her.

November is filled with excitement, surprises, and difficult choices for Claudia, Queen of the seventh grade...and no one can make her choices for her.

As part of her exciting film course, Stacey is making a documentary about teen life in Stoneybrook. The movie creates a conflict with friendships when Stacey pursues tell-all interviews with her friends and enemies.

When Dawn announces that she is moving back to California, the other baby-sitters cannot believe that she would even consider leaving them. 

Dawn and Mary Anne are finally stepsisters and also roommates. When they begin to get on each other's nerves, Dawn comes up with a solution which pleases everyone. 

Stacey and Robert had a stormy breakup. Months later, Robert is moody and depressed, and the only person he'll talk to about it is Stacey.

Stacey is caught in a loyalty tug-of-war between old friends and new. 

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! The BSC is way out of place in the big city. Mary Anne sounds like a walking guide book, Dawn is afraid of everything, Kristy can't keep her mouth shut, and Claudia is jealous of Stacey's friends. Can Stacey be in the BSC anymore?

Visiting her father on the west coast, Dawn is tempted to stay with him when she enjoys the beach, Disneyland, and a wealth of healthy restaurants, but the homesick baby-sitter fears leaving her mother and all of her friends.

When Kristy's friend, Bart, decides that he wants to be her real boyfriend, Kristy is afraid to tell him that she does not feel the same and enlists the help of Mary Anne for courage in expressing herself.

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.
