Sense and Practicality Found Here
This book is a great way for couples to discuss matters that are really important. It is a great way to talk about the things that are all too often "unspoken" even with the greatest of couples. This book gave us a way to make sense of our thoughts, in an easy non-judgmental and open way. It wasn't that we hadn't voiced these ideas or matters, just that we hadn't thought about the matters fully. That is what this book is for: discussing. One of the greatest parts of the book is discussing your family's unspoken rules. My fiance and I had already discussed several of the matters in the book (and thought we had done so successfully), just not as thoroughly as the book asked of us. This really helped us understand each other and our perspectives. Some of the matters in the book seem to be on the naive side, maybe assuming a more modest and conservative lifestyle of its readership (perhaps written especially for couples that haven't gotten to spend a lot of time around each other for extended periods), but there is enough reality to keep topics and discussion flowing. It is an easy fast paced read. This book presents a comfortable and laid back way of discussing the things you may have already thought of but never got the time to bring full circle.

Practical and helpful
Format: Hardcover
This is a great book. My husband and I gave one copy to one of our sons as he started to have relationship troubles; this book helped him immensely in getting to the core of what makes a relationship work. We gave a copy to our other son when he got engaged, and we don't know if he simply read it and responded to the questions or if he used it as a springboard to start conversations with his fiancee. All I see is that they have become more of a team, better at communicating, and very happy as they focus on their future marriage. Note that I said "marriage" and not "wedding" - the more important focus! My husband and I are Christians; the perspective of a Christian couple is clear in this book, but in addition to that, the Parrotts bring professional training and clear writing to the table. Their questions and discussions are insightful and sometimes humorous, making it an easy-to-read book. This is a practical "handbook" for couples at all stages of serious relationships, from pre-engagement through married for many years.

A Must Read For Adults prior to Marraige!
Format: Hardcover
I was a a wedding this past Spring and the minister was so inspiring and even with 37 yrs of marriage I learned something so I asked him what he did with the young couple for pre-marriage counseling and he referred this book! I read it and it is spot on. You don’t need to be a Christian to benefit from it. I purchased 2 more for each of my children who are in their late twenties and dating. It makes you think about the realities of what you really want in a relationship and to focus on what is important. Highly recommend!
