I would read The Last Unicorn by Peter S. Beagle. It's one of my favorite books of all time. I don't know how old your kids are but you could maybe read it to them. It's magical and "says" so much that's hard to explain/express and shows transformation and how it happens, etc. Mostly I read children's books, the C. S. Lewis Narnia series, Lloyd Alexander's Chronicles of Prydain, lots of Madelaine L'Engle, David Eddings, A Red Heart of Memories by Nina Kiriki Hoffman, definately not a "children's" book but up there in my top 3-5 books of all time.

Nonfiction I would read Crones Don't Whine: Concentrated Wisdom for Juicy Women by Jean Shinoda Bolen and The Art of Becoming Human by child psychiatrist Mary E. Mercer (The book is beautifully written/profound and extremely comforting that "It" is all going to come out all right. Was wonderful for me because of how "long" therapy was taking and how hard it was to figure out what was "happening").

Basically, books about people on "journeys" through life.
