A broken family of former slave owners. A pregnant woman awaiting her lover's arrival. A veteran that lost a hand in the civil war. A gathering with unexpected guests. In Sister Séance, a historical feminist horror novel by Aimee Parkison, a Halloween celebration brings together a range of characters in Concord, Massachusetts, and brings them face to face with their pasts.
Sister Séance is set shortly after the Civil War and centers around the history of two families: the Turners and the Haydens. A Dumb Supper, a meal where guests communicate without speaking, serves as the catalyst that gathers both families and most of the town along with two unplanned guests, the Usherwood Twins, a pair of mediums.
