As a licensed social worker/grief counselor for a local hospice, I find this book very helpful for me in my work with grieving people. I suggest others read it to help them with their grief. Grief is something Americans "don't do" well because it isn't socially acceptable. This books helps people understand that grief and mourning are okay, a part of a healthy life, and it empowers people to help them through the grief, not to get stuck in it.
