I find this book as a necessary read for everyone, simply because we are all destined to die. Death, especially in American culture is a taboo topic not to be brought up until a death in the family occurs. The only issue is that in the midst of grief people don't always make the best decisions. I can say that I have experienced seeing the nasty side of people who have fought over belongings of a deceased because the person in question never thought to write a will.
This book does not reflect on the gory details of the funeral business but rather gives you a perspective that as a reader is quite valuable, such as information you need to know. It is never too early to write a will, never too early to think about either wanting a burial or a cremation etc etc.
Funerals are not easy nor are they cheap, better to do the research now to save up, rather than leave the grief and the stress to your loved ones. It's your body, so make sure you get a say in what happens after death.
