I'll pick up any book written by Gary Chapman on relationships. He has keen insight into the sometimes unstable, all the time unpredictable, lives of married couples.
Now You're Speaking... is a very practical book that I enjoyed. I liked the fact that he used real life couples in his examples and illus.. I also appreciated the fact that he summarized his chapters at the end each chapter. I felt like he was taking the old formula that my jr. high English teacher used to teach compostions. Tell them what you're going to tell them, tell them, then tell them what you told them. That's exactly what Chapman did.
The book you can tell is designed to be read by someone who has already reach the 5 love languages. You can enjoy the book without having read 5 love languages, but you certainly won't get everything out of it that you could have.
So if you are looking for a great read on relationships, and have already read Chapmans book, "The Five Love Languages" grab this and enjoy, if not, grab The Five Love Languages, it really is the better book.
