Are You There God? It's Me, Margaret

Re-read on audiobook. I remember hiding in the library at school reading this in 4th grade, being absolutely shocked about bras and periods (we didn't have the internet back then, friends!). I did not, however, remember the very frank discussion of religion. She's “no religion” and goes on an exploration tour through Judaism, Christianity, and catholicism to see what feels right to her. For a YA book from 1970, I am impressed.
