"In the summer of 1990, 14-year-old Trevor Riddell gets his first glimpse of Riddell House. His father, Jones Riddell, has brought Trevor to Riddell House for the summer with a goal: he will join forces with his sister, Serena, to dispatch Grandpa Samuel--who is flickering in and out of dementia--to a graduated living facility, sell off the house and property for development into 'tract housing for millionaires,' divide up the profits, and live happily ever after. But Trevor soon discovers there's someone else living in Riddell House: a ghost with an agenda of his own"-- Provided by publisher.
