When a terrible fight breaks out among the four Baby-Sitters Club friends, Mary Anne is left to her own devices. She has to sit by herself at lunch, make new friends, and deal with her overprotective father without advice from the BSC gang. But the worst part is when she faces a terrible baby-sitting predicament, and she can’t find any help.
Luckily, Mary Anne rises to the occasion. Not only does she handle all her problems with aplomb, she also manages to get the BSC back together again.
