While I Was Gone by Sue Miller
There was much in this novel that I could relate to, a characteristic of good fiction. After a rocky young adulthood in the 70's Jo Becker becomes a respected veterinarian, wife of a minister and mother of 3 daughters. Then someone from her past reenters her life and things change dramatically. This is about relationships and emotions with an unexpected twist. There is one graphic description of a sexual encounter between Jo and her husband that seemed somewhat out of place and unnecessary. I will look for other books by this author.
