But once installed as the doctor's wife in a nowhere corner of Maine, bordom sets in...until an unforseen moment of personal rebellion changes everything, especially as Hannah is forced into breaking the law. For decades, is one transgression in an otherwise faultless life remains buried. But then, in the charged atomosphere of America after 9/11, her secret comes out and her life goes into freefall.
