Writer Nancy Cobb knows first-hand how the death of a loved one changes your life forever. Her father committed suicide, her mother died after a long battle with Alzheimer's disease and her close friend Elaine died of cancer. Cobb's personal experiences with grief are the inspiration for her new book "In Lieu of Flowers: A Conversation for the Living." The book is part memoir--and part advice column. Cobb wants people to accept the "divine intersections" where the living meet the dying. She says she wrote it as a way help her deal with her overwhelming grief.
