Are You There God? It’s Me, Margaret by Judy Blume
It’s okay to be of no particular religion … as long as you still believe in God.
No one ever told Margaret Simon that eleven-going-on-twelve would be such a hard age. When her family moves to New Jersey, she has to adjust to life in the suburbs, a different school, and a whole new group of friends. Everything is changing. And there are some things about growing up that are hard to talk about, even with your best friends. So Margaret finds someone else to talk to.
