Silas Flood is a broken man in a broken country. Nine years have passedsince the end of the American Civil War and Flood is helpless to escapeits shadow.
 
In the summer of 1874 he is dispatched to the mountain village of Moriah, Vermont to investigate sensational claims of supernatural happenings at a wayside inn. There the brothers Thaddeus and Ambrose Lynch are said to converse with spirits and summon the dead.

In Moriah, Flood encounters others like himself: a grieving couple, a childless widow. By day he questions the Lynch brothers who prove less than forthcoming. They too are haunted by buried secrets, old ghosts. In the evenings he attends séances where the resurrected dead dance and sing and give comfort to the living. As Flood investigates the true nature of these phenomena he is forced to come to terms with his own past and with the hold it has upon him.

Moriah is a work of the historical Gothic which recalls the Victorian fiction of Sarah Waters, Michael Cox, and Charles Palliser.
