Query: Summer Sisters

Judy Blume just has this knack for getting it right. She understands what it's like to be an awkward kid growing up and an over-hormoned kid growing up and she takes these two characters from puberty into teenagers into young adolescence to adulthood with the trials and tribulations that go with it. I think any female can relate to some aspect of the story.
