My wife found this one, along with others, to get some perspective on how we might approach our role as parents as our kids become adults. Other titles included 'your teenager is not crazy' (or something like that), but this is the only one I got to. The book is written in a non-dogmatic style but nonetheless Christian in its outlook, and somewhat American as well. The latter aspect is easy enough to work around ( differences in college/university, for example), and while Christians are likely to enjoy this more easily, I don't see why others might not get something from it. To a large extent, the authors are aiming to help parents think through individual situations amidst tensions in values.
Some of the issues include work, money and marriage/inlaws/grandchildren, each of which can be points of joy when things go well, stress when children have to struggle through difficulties and in some cases pain for all when relationships break down. And this was probably the key message for me - continuing to stay connected as children grow up and respecting their adulthood. I may go back to this at some point to review specific situations but overall I found that the process of reflecting on the various topics helped me continue to appreciate the privilege and responsibility of being a dad and know that I can continue to enjoy this as I enter a new stage of life.
