What was the theme in Deenie by Judy Blume?

A teen dealing with divorce of her parents...I think. I never read the book, but I have the book. I think Judy Blume is a blessed writer. One of my most fav of hers is ARE YOU THERE GOD, ITS ME MARGARET.....a great book for young girls, 10-14 or so. Give or take a year either direction.
