Ellie and Henry are young, rich, and engaged. When Ellie’s eccentric Aunt Kate asks her to house-sit at her palatial estate in Burton, Virginia, Ellie is happy to oblige. She feels right at home there with the nearly invisible housekeepers and the plethora of pets, but conventional Henry finds Aunt Kate and her lifestyle a little hard to take. After he leaves, Ellie realizes that there are disturbing secrets about the local aristocracy buried in a dusty old book she has carried into the mansion, and her sudden interest in the past is attracting a slew of unwelcome guests—some of them living . . . and some, perhaps, not. But there are no such things as ghosts, are there? And the terrible vengeance that Ellie and her friends seem to have aroused—now aimed at them—surely cannot be . . . satanic.
