"For Better or For Best (Understanding your Husband)" by Gary Smalley
Almost any book on marriage by Smalley, and she may profit from reading "Love is a Decision".
"Healing the Hurt in Your Marriage" by Dr. Gary & Barbara Rosberg
"When Love Dies" by Judy Bodmer
Christian bookstores have tons of books on M. If it were me, I would feel more comfortable choosing something in that type of location b/c there are some crazy things in a secular bookstore.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
