Are You There God? It’s me, Margaret by Judy Blume

Margaret Simon, almost twelve, likes long hair, tuna fish, the smell of rain, and things that are pink. She’s just moved from New York City to Farbrook, New Jersey, and is anxious to fit in with her new friends—Nancy, Gretchen, and Janie. When they form a secret club to talk about private subjects like boys, bras, and getting their first periods, Margaret is happy to belong.
