Kristy, Claudia, Mary Anne, and Stacey try to be prepared for anything when they baby-sit. So when they hear about the Phantom Caller, a jewel thief who's been breaking into nearby homes, they come up with a plan to keep their kids safe. But when Claudia and the other girls start receiving creepy phone calls while they're out on jobs, they start to get really spooked. Will the mystery caller scare off the BSC?  

Mary Anne has never been a leader of the BSC. So when a fight breaks out among the club's four members, Mary Anne feels a little lost, unable to depend on Kristy, Stacey, or Claudia anymore. Sitting by herself in the cafeteria is bad enough; when Mary Anne has to baby-sit a sick child without any help from the club, she knows someone has to take action. It's time for Mary Anne to step in and save the day! 

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. The truth is, she likes her doctor and just wants to spend her time being a normal girl and hanging out with the Club. Can Stacey find the courage to be honest - with everyone? 

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! 

Claudia's sister, Janine, is too busy being smart to be nice to anyone - even their grandmother, Mimi. But Claudia doesn't have to see Janine too much this summer, since the Baby-Sitters Club is starting a new play group. It's going to be so much fun! But then Mimi has a stroke, and the whole summer changes. Now Claudia is "Mimi-sitting," and Janine is no help at all. How can the Kishi sisters get along when Janine is always so mean?

Stacey and Mary Anne are baby-sitting for the Pike family for two weeks at the New Jersey shore. Things are great in Sea City: There's a gorgeous house right on the beach, a boardwalk, plenty of sun and sand...and the cutest boy Stacey has ever seen! Mary Anne thinks that Stacey should leave Scott alone and focus on the Pike kids, but Stacey's in love. Looking for reasons to hang around his lifeguard stand takes up all of her time, which means Mary Anne has to do the job of two baby-sitters.

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! They criticize Kristy's clothes, make fun of the Baby-Sitters Club...and worst of all, they laugh at Louie, Kristy's pet collie, who's going blind. Nobody does that and gets away with it! Kristy's fighting mad, and she's not going to put up with a Snob Attack any longer - and neither is the BSC!

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?

Claudia has always been the most outrageous girl in her class...until Ashley Wyeth comes along. Ashley's really different - she dresses in hippie clothes, wears six earrings and work boots, and is the most fantastic artist Claudia has ever met. Ashley says Claudia has artistic talent, too, but thinks Claudia should spend more time on her "calling" and stop wasting time on the Baby-Sitters Club. The baby-sitters are sick of Ashley Wyeth, and they feel like Claudia is a traitor. Claudia has to decide: either the BSC or the new girl - one of them's got to go!

Mary Anne used to have to wear her hair in braids, keep her room painted pink, and ask her dad before she did anything. But not anymore. Mary Anne's been growing up...and the Baby-Sitters Club members aren't the only ones who have noticed. Logan Bruno likes Mary Anne! He has a dreamy southern accent, he's awfully cute - and he wants to join the Baby-Sitters Club. The baby-sitters aren't sure Logan will make a good club member. And Mary Anne thinks she's too shy for Logan. Life in the BSC has never been this complicated - or this fun!
