would give this a three to 3.5. Ater 18 years of marriage , Kate has settled into a pattern of comfortable routines with teenagers, supporting her husband in his business and taking care of their home. Then one day she discovers a suspicious number on her husbands cell phone. Six years ago she accused him of infidelity which he denied. Now she must decide whether to follow her suspicions at the risk of losing everything or true the man with whom she has built a life. She is confronted with surprising truths about friends , family and her own motivations. An interesting premise for a book, and told from all three perspectives: the wife, the husband, the mistress. I did like that part of it but by the time you reach the mistresses viewpoint you are tired of reading the same story again - maybe necessary, but repetitive and boring. Seems reviewers either loved this or disliked it. It did resolve rather abruptly but it does a good job of looking at viewpoints.
