Definitely worth a read/listen for anyone going through this. I think the reason other reviewers say that this book isn't terribly helpful in a practical way is the unfortunate reality that there isn't a one size all, simple solution to the problems divorce brings into a family. The best an author can do is help you know you're not alone and show you what has worked for other families to give you hope and to get you searching creatively for solutions for your own situation. I think the authors do this. They also make a number of practical suggestions, especially towards the end of the book. However, I thinking helping put the feelings and pain into words is the most powerful thing the book does. Repetitive? Yes, but also, validating.
It would have been 4 stars for me except for the chapters stuffed full of broad generalizations about men and women. It seemed to me to be written from a strong feminist perspective and I felt like it didn't always give full credit to the potential male perspective. That being said, as a woman, I can't confirm this.
It's also important to note that this is currently the only book written on this topic. With so little information available, it's hard not to feel both thankful for these authors and at the same time frustrated at the lack of resources. It does feel like a "beggers can't be choosers" type of situation, so maybe take that into perspective when considering the reviews.
