Duncan McNeil is staring mistrustfully at a photograph of his daughter, Amy. She appears to be at or near her present age of ten, but the studio’s dated stamp on the back indicates that the photo was taken nearly a year before her birth. More alarming, however, is the beautiful woman standing beside Amy, a woman with whom he had an affair in the periphery of his new marriage, during the time when Amy was conceived. And the fact that this photograph has been in his wife’s possession for more than a decade is perhaps the most disturbing element of all.
Duncan’s wife Rachel doesn’t know about his affair with this woman, but he will soon tell her. And upon that revelation they will begin a journey that will take them clear across the continent, from California to Massachusetts, then ultimately into the boundless, uncharted territory of the human collective. There, a devil is waiting; the penultimate personification of evil. And he goes by the name of Mr. Gamble.
