Hi! I believe I can be of help with this issue. First, let me say I applaud your proactive approach. Good for you. It will pay off. I know because I see in my office families who didn't work at it from the start! While there are many books out there about the mother in law and daughter in law relationship, there aren't any I've seen specific to the fathers. But your husband will also gain from these two books. I think these two are among the best out there.
