Seven years after Boston homicide detective Abigail Browning's FBI Special Agent husband, Chris, was shot dead on their honeymoon on Mt. Desert, Maine, 32-year-old Abigail returns to the resort island to try to find Chris's killer so she can move on with her life. The relentless detective risks both physical and emotional pain as she searches for the truth among the local people and the wealthy summer families who were her late husband's friends. A multitude of well-drawn suspects and the rugged Maine setting help offset some unrealistic initial interludes between Abigail and a potential new love interest, Owen Garrison, a neighbor who was the first to inform her of Chris's murder.
