If you haven't yet read The Divine Secrets of the Ya-Ya Sisterhood, do it. And before the movie comes out because no movie can capture the way that the book reveals the poignancy and complexity of relationships among these "lifelong friends who stage a rather unorthodox intervention to help a young playwright unravel the truth about her complicated, eccentric mother, find forgiveness and acceptance, and let go of her painful past." I think that even Helene Cixous would approve of the novel.
But even if you don't have time to read the book, go see the movie anyway. I can't wait!!
