Here is another OBAG--oldie but a goodie. If you have never read, it is time for you to pick it up. If you have read it, it might be time for a re-read.
Margaret is in 7th grade, and she and her friends are going through the normal things that 7th grade girls go through. Margaret is struggling because her parents have decided that they will let her make her mind up about religion. Her father was raised in the Jewish faith, and her mother was raised in a Christian household. When they got married, none of their parents were happy. Her mother's parents completely disowned her, and Margaret has never met them. Now that Margaret is 12, she starts wondering about God and begins to seek him by attending worship services with various friends and her paternal grandmother. This book is funny, yet poignant. Give it a try.
