Healthy Marriage Reading List

Sarah and I are in the midst of premarital counseling again. Not for us. We are the counselors, for the third time. This is one of my favorite parts of being a pastor. I love talking about how to have a good marriage.
Sarah and I really enjoy reading books on how to have a healthy relationship, so I thought I'd share some of the books we've found helpful and are recommending to the couples we counsel.

The Five Love Languages - Gary Chapman (very helpful for learning how you both give and express love)
His Needs, Her Needs - Dr. Willard Harley, Jr. (helpful for understanding that our needs are fundamentally different and how to satisfy those different needs)
Getting the Love You Want - Harville Hendrix (a deeper psychological book, helpful for bringing communication to a deeper level and identifying how your family history may still be impacting your present)
Romancing Your Husband - Debra White Smith and Daniel W. Smith (the theory and ideas for romance)
Romancing Your Wife - Debra White Smith and Daniel W. Smith (same, but the other way around; Get both of these books, but don't let your spouse read yours.)
The Act of Marriage - Tim and Beverley LaHaye (Yes, before Left Behind, they were writing about sex! Hard to believe, I know. This book is an interesting mixture of cheesy, strangely old-fashioned, profound, and scientific. Over all, still worth the read, especially to understand the - um - nuts and bolts of sex.)
Sheet Music - Kevin Leman (This is a very bold Christian book about sex and intimacy. He goes all out in explaining and encouraging married couples to have a great time with each other. A must read, together!)
Every Man's Battle - Steve Arterburn, Fred Stoeker, with Mike Yorkey (ed.) - (This is a must read for every man and for every woman married to a man! It explores the battle every man faces to stay sexually pure. Don't miss this one!)

We still haven't found a book we really like as a basic text for premarital counseling. Any ideas out there?
