Stacey doesn't like to tell everyone that she has diabetes. Her friends in the Baby-Sitters Club are supportive, but Stacey has lost other friends who didn't understand her condition. Stacey's parents don't seem to understand, either; they're constantly taking her to new doctors.

As the newest member of the BSC, Dawn is eager to prove herself. So when a big job comes along, she jumps at the chance to show everyone what she's made of. The Barretts are even more challenging than Dawn expected. The house is a mess, Mrs. Barrett is unreliable, and the kids are out of control. Dawn knows she's a great baby-sitter, but this is impossible! She only knows one thing for sure - a member of the BSC never gives up! 

Dawn has always thought there was a secret passage hidden in her house. But that doesn't explain why creepy things happen when Dawn's at home, or the spooky noises coming from behind her bedroom wall. Dawn is sure there's a ghost in her house! And so are the other Baby-Sitters Club members. But they're so busy with their jobs that they don't have time for a ghost hunt. Will Dawn and her friends solve the mystery...or will Dawn have to share her house with a ghost?

After Kristy's mom got married, her family moved to Watson's house in a new neighborhood. But the kids there aren't very friendly - in fact, they're total snobs!

Kristy's fighting mad, and she's not going to put up with a Snob Attack any longer - and neither is the BSC!

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!

Mary Anne should never have thrown away that chain letter she got in the mail. Ever since she did, bad things have been happening - to everyone in the Baby-Sitters Club.

Mary Anne has to do what the note says. But who sent the charm? And why send it to Mary Anne? If the BSC doesn't solve this mystery soon, their bad luck might never stop!

Maybe Jessi would like to be a star, too!

Mallory and Claudia are helping Stacey unpack from her move back to Stoneybrook when they find an antique trunk in the McGill's attic.

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! 

Claudia, who has always been very different from her sister, comes to the conclusion that she must be adopted. 

To a New York City girl like Stacey, the fact that an old - supposedly haunted - house in Stoneybrook is being torn down is no big deal. But then her friend Kristy discovers the house was built on a graveyard, and when Stacey sees a horrible face in one of the windows, she wonders if the house really could be haunted!
