I got this book for my son and daughter-in-law. My son is active duty Navy. My daughter-in-law told me "This book was exactly what they needed!" She also said "Our communication is much more open because the book has taught us(them) how to communicate in the manner of which the other person needs to understand what the other is trying to convey." Yes, it's written by Gary Chapman, but it's not filled with biblical teaching. Couples who are military have a bunch more obstacles than couples who are not military. There is another book in this series called "The Five Languages of Love." I recommend both books!
