Book excerpt: This is a read-and-understand, lock-it-in-with practice book that will enrich your relationship with your loved one. For thirty years Foster and Hermie Cline have worked with other couples individually and in groups, in this country and abroad, helping them learn how to do the same thing: build lasting relationships. They've worked with couples by the fireside in their home, and on houseboats lashed together on America's lakes. They've worked with couples around the campfire, and in many retreat centers. The wisdom gained through all these years and experiences culminated in a book that is enjoyable and effective for couples wishing to make the most of their relationship. MARRIAGE - Love and Logic includes a bonus DVD packed with couple laugh-and-learn vignettes and links to a website questionnaire that will help you understand yourself, your loved one, and your relationship along nine different scales.
