I've just finished watching Divine Secrets of the Ya-Ya Sisterhood. It was a cute movie, but was very different from the book. In the book, the daughter, Sidda, has sequestered herself at a friend's cabin in the Seattle area, where she is able to page through the scrapbook. In the movie, the Ya-Ya's, minus her mother, kidnap her and take her to Louisiana and tell her stories.
Basically, the entire modern day story of the film is different than that of the book. There is also a lot that was left out of the film.
Some things were changed as well. In the book, it's an elephant ride that teaches Sidda not to be afraid. In the movie, it's an airplane ride.
I recommend the book, and the movie isn't bad either.
I think that the book is more in the tradition of Fried Green Tomatoes.
