Lake Superior's Big Bay Point lighthouse has illuminated rocky shoals for more than a hundred years, but these days the stout old tower shelters women and children from emotional turbulence. Celeste Brookstone is the new owner and director of the safehouse, having found a satisfying life-mission following the murder of her daughter, Pilar. That the shelter is so close to Hawk Haven Prison, where Pilar's murderer is serving a life sentence, seems immaterial to Celeste—after all, she played a part in seeing Chad Wilbanks locked away in maximum security isolation. When Chad escapes, however, he too is on a mission: settling the score with Celeste. The worst November storm on record creates the perfect cover for Chad's approach, but Celeste is better prepared than he expects. What Celeste is not prepared for is a shocking truth in the form of a ghost from her past.
