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. 

When Mary Anne is woken up in the middle of the night by her cat, Tigger, she immediately knows something's wrong. Then she smells the smoke...and hears her father yelling her name. Mary Anne's house is on fire - and she makes it out right before everything burns down. Now Mary Anne doesn't know what to do. All of her possessions are...gone. Her house is...destroyed. Will Mary Anne be able to get her old life back? Will her family move away from Stoneybrook...for good?

At first, Claudia hated going back to seventh grade. But things are definitely improving. She's on top of her schoolwork, she's made some great friends, and her new classmates really look up to her - so much that they nominate her to be Queen of the Seventh Grade. And when the votes come in, the results are clear: Claudia's not just adjusting to seventh grade, she's ruling it!

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!

Mallory comes down with mono and her parents make her quit the Baby-Sitters Club....

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?

In one of the strongest Babysitters Club books ever, the club must deal with a client who is abusive toward his children. Ann M. Martin addresses a difficult and important topic in her characteristic sensitive and informed style.

When her troubles in school culminate in her being dropped back to the seventh grade, Claudia struggles with feelings of failure while adjusting to classmates outside of the Baby-sitters Club.

Mallory and Claudia are helping Stacey unpack from her move back to Stoneybrook when they find an antique trunk in the McGill's attic. Stacey doesn't want the dusty thing, so she gives the trunk to Mallory...who finds an old diary at the bottom of it. The diary belonged to Sophie, a girl who lived in Stacey's house in the 1890s. As Mallory reads deep into Sophie's diary, she discovers a mystery on their hands to solve, because Stacey's house isn't big enough for her, her mom...and a family of ghosts! 

The rest of the baby-sitters are shocked when Mary Anne, tired of being a plain Jane, gets a chic new haircut and a new wardrobe, and their reaction enrages the excited Mary Anne. 

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.

Naturally, Jessi is thrilled when she earns the lead role her in dance school's latest ballet. But someone in class wants her out of the show. First Jessi's toe shoes are stolen.

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! Dawn's going to do everything she can to help her charges win, even if Margo's only talent is peeling a banana with her feet. But then Kristy, Mary Anne, and Claudia are helping Karen, Myriah, and Charlotte enter the contest, too. It's hard to tell whether the competition is fiercer at the pageant - or in the BSC!
