This wonderful book had a strong, female protagonist who was clearly intelligent and eloquent. Harriet eavesdrops, peers through windows and skylights and records her impressions in a notebook. She has regular "spying" stops in the Upper East Side Manhattan neighborhood where she lives. She knows quite a bit about the people in her neighborhood, thanks to her observant nature.
Harriet is a student at the prestigious Gregory School, where she has an assortment of friends -- scientific, aggressive Janie, meek, retiring Beth-Ellen and a fun loving boy called Sport.
When Harriet's notebook falls into the hands of her classmates, problems arise big time. Harriet has a baptism in fire trying to redeem herself in their eyes. Meanwhile, Harriet's nanny is leaving to get married, her formerly disinterested parents are pushing more into her life and lastly, Harriet herself is maturing.
I loved this book so much as a child and do today. This book even inspired me and countless others to keep a notebook. It was a book about the empowerment of a strong female character.
