Query: My favorite book of all time

I first read "A Wrinkle in Time" by Madeleine L'Engle when I was in fifth grade, and it has been my favorite book since that time. It has a great message of love, family, and caring for others. My son also read it when he was in fifth grade, and enjoyed it a great deal. I purchased this copy to give to my daughter, who is in fifth grade this year.
