Surviving the Halifax Explosion is one thing, but how do Lucy Caines and her wayward husband, Harry, a couple who lose everything to the event's horrors, make peace with their grief? Rebuilding on the rustic shores of Halifax's Northwest Arm, steps from where the shaft of the Mont Blanc's anchor lands that fateful day in 1917. But coping with the disappearance on that day of their infant daughter, they descend into an isolating denial: Lucy through guilt and reticence, and Harry through drinking and gambling. Despite the birth of a treasured son, each faces a future clouded by fear and apprehension. Then, fifty-two years after the catastrophe, Harry suffers a stroke. Lucy confronts the miracle of their survival and their debilitating loss, re-examining the past and her role in its making, and struggling to become the author of her own happiness.
