I just ordered "Divorce Busting" and "The Divorce Remedy" through a friend of mine, so that WW does not catch on.

What exactly is the difference between the two? and should I just had ordered the one (Divorce Remedy) seems to be a newer version? Just wondering if I am buying two nearly identical books?
