"Here is the truth, this is what I know: I was walking on the beach with Emma. It was cold and very foggy. She let go of my hand. I stopped to photograph a baby seal, then glanced up toward the Great Highway. When I looked back, she was gone."

Life changes in an instant. Like on a foggy beach, in the seconds when Abby Mason—photographer, fiancée, and soon-to-be-stepmother—looks into her camera and commits her greatest error.

Six-year-old Emma vanished into the thick San Francisco fog. Or into the heaving Pacific. Or somewhere just beyond: to a parking lot, a stranger's van, or a road with traffic flashing by. Devastated by guilt and haunted by her fears about becoming a stepmother, Abby refuses to believe that Emma is dead. And so she searches for clues about what happened that morning—and cannot stop the flood of memories reaching from her own childhood to illuminate that irreversible moment on the beach. Now, as the days drag into weeks, as the police lose interest and fliers fade on telephone poles, Emma's father finds solace in religion and scientific probability—but Abby can only wander the beaches and city streets, attempting to recover the past and the little girl she lost. With her life at a crossroads, she will leave San Francisco for a country thousands of miles away. And there, by the side of another sea, on a journey that has led her to another man and into a strange subculture of wanderers and surfers, Abby will make the most astounding discovery of all—as the truth of Emma's disappearance unravels with stunning force. A profoundly original novel of family, loss, and hope—of the choices we make and the choices made for us—The Year of Fog beguiles with the mysteries of time and memory even as it lays bare the deep and wondrous workings of the human heart. The result is a mesmerizing tour de force that will touch anyone who knows what it means to love a child.
