The Love Hunter

Larry Quinn lives in a college town in rural Minnesota. He is dying from multiple sclerosis and his best friend, Chris MacKensie, has fallen in love with Larry's wife, Rachel. The love for the dying and passion for the living form an uneasy bond, as the three of them face the truth of life together....

This book was written in the early 80's, I found it at a yard sale. At first it was kind of draggy but then towards the end it was intense. Chris is deciding if his love for his friend or his love for his friend's wife is stronger.
