This book is used in the Family Dynamic's "Dynamic Marriage" course. We've been through the course 3 times. The first time, we were newlyweds and learned a lot about each other. The second time, we'd been married a little while and worked through some issues we needed help in. The third time, we had a great marriage, and we made it even better. It's a wonderful book and an excellent course. I'd recommend it to anyone. The course and the book together have been an indispensable tool in our marriage.
