Query: This book change my life

I knew there was something wrong with my marriage, but couldn't put my finger on it. This book opened my eyes and woke me up! I have to be honest, I cannot tell you much about the quality of Mary Susan Miller's writing style, I was too busy trying to absorb all the information.Please don't hesitate to buy it; the price is small compared to the knowledge you will gain. I read this book cover to cover, then read it one more time and passed it on to my daughter. I'm going to buy a copy for my Mom, and one for each of my sisters. I feel this information is of value to every woman, no matter what kind of relationship she is in.
