Jessi can't believe it. Her dreaded Aunt Cecelia is moving in to take care of Jessi and her brother and sister. How humiliating - Jessi's going to have a baby-sitter! Plus, Aunt Cecilia is a drill sergeant. She tells Jessi when to go to bed and how to wear her hair - and she even forbids Jessi to go to a Baby-sitters Club meeting. Jessi knows she's old enough to take care of herself - but how can she tell Aunt Cecelia that?
