By some ghost writer using the name of Anne M. Martin. New York: Scholastic, 2000.
I can see what the ladies at Snark Squad mean when they talk about the BSC books.
Kristy makes everything about herself and is of course bossy. Throughout this famous children's literature series she never gets less bossy. In "Graduation Day", Kristy makes graduation from middle school all about her by worrying over whether the Baby-sitters Club will continue when the girls start high school. See, Kristy has such low self-esteem that if she's not in charge of something she can't make it through life.
Also, as the Snark Squad ladies say, Claudia does seem to be retarded. She can't even spell Mary Anne correctly, even though she's probably seen it in the club book hundreds, if not thousands, of times.
The other screwed up thing about this book is it reads like the last in the series, when in fact there are a couple more after this. Mary Anne and her family move into their new house in the summer after graduation, but "Graduation Day" has them already in the place.
