Adam Connor thinks he is doing the right thing, pulling his car with his pregnant wife and two children off I-80 during a Christmas morning snowstorm. A car has crashed into the wooded thicket separating the east and west lanes, and he is overwhelmed with the need to help. Fifty feet into the woods he finds a car with the driver dead and the passenger dying. When the unconscious passenger's breathing stops and no pulse can be found, Adam brings the young woman back to life with CPR just before the EMTs arrive. Emerging from a weeklong coma twenty-eight year-old Addie Harris is told she is now a widow. She is also told that she is alive only because of a Good Samaritan. As Addie recovers, her few attempts to locate the Samaritan go nowhere and she eventually returns to the life of meaningless sexual encounters she had been living before meeting her late husband. Several months later, Addie discovers the heart-wrenching headline of a newspaper article. And so begins the search for the man to whom she now owes more than her life. A search that eventually leads to Dublin and the coast of Ireland, and her savior who possibly now needs someone to save him.
