On Death and Dying began as a theoretical book, an interdisciplinary study of our fear of death and our inevitable acceptance of it. It introduced the world to the now-famous five stages: denial, anger, bargaining, depression and acceptance. On Grief and Grieving applies these stages to the process of grieving and weaves together theory, inspiration and practical advice, all based on Kübler-Ross and Kessler's professional and personal experiences, and filled with brief, topic-driven stories. It includes sections on sadness, hauntings, dreams, coping, children, healing, isolation, and even sex during grief.

"I know death is close," Kübler-Ross says at the end of the book, "but not quite yet. I lie here like so many people over the years, in a bed surrounded by flowers and looking out a big window….I now know that the purpose of my life is more than these stages…It is not just about the life lost but also the life lived."

In one of their final writing sessions, Kübler-Ross told Kessler, "The last nine years have taught me patience, and the weaker and more bed bound I become, the more I'm learning about receiving love."

On Grief and Grieving is Elisabeth Kübler-Ross's final legacy, one that brings her life's work profoundly full circle.
