As a pastor, I give this book to every young couple whose ceremony I conduct. I have also given it to married couples whom I feel could benefit from such information. I have been using this book for the past forty years and have found it to be one of the best.
The half a star is for the good information on biology. However, I am terribly dissapointed in some of the advice the LaHaye's give. Suggesting that if you've cheated on your spouse or had premarital sex you don't have to tell...as long as you're "really sorry" is ridiculous. I can't imagine the damage this would do in a marriage-never mind the potential to pass an std onto your spouse or the fact that people who are truly repentant should be willing to confess. Some other responses also seem to lack common sense and respect for the other spouse.
