Not sure what the other reviewers are talking about, but I have the exact book cover and title on my bookshelf and it was a very good read.
I read this book when I was going through the "trying to save my marriage phase". It has practical biblical principals that really work. I tried some of them and it kept my marraige going for a little while longer, until we just lost intrest and fell out of love with each other, but that has no reflection on the book. It still is a good self-help book if you really and truly want the help.
