It's the first day of a new school year, and while Mary Anne doesn't know what to expect from the eighth grade, she's looking forward to getting back into the swing of things. One thing she definitely doesn't expect is to meet Logan Bruno, who just moved to Stoneybrook! Logan has a dreamy southern accent, he's awfully cute... and he might be interested in joining the BSC. But the baby-sitters aren't sure if Logan would make a good club member, so...

"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!" --Page 4 of cover.

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?" --P.

"Stacey's invited her friends from the Baby-sitters Club down to New York City for a long weekend. But what a mistake! The Baby-sitters are way out of place in the big city. Mary Anne sounds like a walking guide book; Dawn's afraid of everything; Kristy can't keep her mouth shut; and Claudia's jealous of Stacey's friends. Does this mean Stacey can't be the Baby-sitters' friend anymore? Will the Baby-sitters Club fall apart?"--Page 4 of cover.
