Mallory Pike has always wanted to be a member of the Baby-sitters Club--they're so much fun to be around, and she's practically a baby-sitter already. Now the club members have invited Mallory to a meeting. This might be her big chance! But the BSC isn't making it easy--they make Mal feel like a baby on a job, and make her take an impossible written test. Mallory's beginning to think she doesn't want to be a part of the BSC . . . or maybe she and her new friend Jessi should start a club of their own. It's time to show those Baby-sitters what a couple of new girls can do!
