Overall, quite a good book on how to deal with and respond to loss. It includes both death and divorce, as well as other types of losses (unemployment, bankruptcy, moves, etc.) in its subject matter and does a good job of emphasizing that every person and situation is unique, that there's no one "right way" to heal, and that it's not a quick, fast-food process. At the same time, though, the author still tends to project that there's a "normal" timeline for moving through loss...so it contradicts itself at the same time. I would have liked a bit more attention, emphasis, discussion, or recognition that the "normal timeline" isn't as realistic or common as Deits makes it sound. But I could definitely be colored by my own experience of loss and how it hasn't fit into tidy timelines, and other readers might not have the same sensitivity to this issue as I do.
This book includes many exercises to try to help move through your loss. I didn't try any of them, so I can't attest to their effectiveness or not. I already attend a support group for young widows and widowers, though, so the purpose of many of the exercises in this book are already fulfilled, for me, by the discussions we have holistically in our group. For someone who doesn't have such an established network, however, these exercises could be invaluable--particularly if you have been avoiding dealing with the underlying issues.
The book's inclusion of what it calls "quiet losses"--the loss of innocence after childhood sexual assult, the loss of body parts, the stigma still associated with dying from AIDS--was intriguing. It's a topic you don't see too often in books on grief and loss (from what I remember reading thus far, at least), but it's worthy of even more merit and attention.
