Are you there God? It's me, Margaret by Judy Blume

I found out about this book because of the film trailer and I'm so glad I did. It's a beautiful and fun coming-of-age novel, excellent for pre-teen girls and for women who want to remember those days.
What I loved most about the book was how open-minded the main character was about religion. She was curious, inquisitive, and willing to accept many possibilities.
I just can't wait to see the film.
