This book is a compilation of long-hand written notebooks that C.S. Lewis wrote after his wife's death from a long battle with cancer. In his many writings he questions his faith, how God can be a good deity and allow this kind of pain, and screams out to the universe in agony. In the end Lewis comes to terms with his grief and his faith and found that " bereavement is a universal and integral part of our experience of love."
I highly recommend this book no matter what your loss. To read how eloquently and at the same time at a primal level that Lewis is able to express his anger and sorrow is an important lesson for any griever. It's okay to have these feelings, there's nothing wrong with you, and Lewis is testament to the fact that someone can question everything and survive.
