The book Boundaries in Marriage is written by Dr. Henry Cloud and Dr. John Townsend. These two authors are, what I would consider, some of the best of the best in their field. This book was written, as a second, to the book named Boundaries. This oldie but goodie is probably one of my favorite when referencing the field of marriage and family therapy. There is a newer version of this book listed on Amazon.com. If you are only going to suggest one book for those suffering in their marriage, this would rank as one of the top for me.
