Summer, 1990. Fourteen-year-old Trevor Riddell gets his first glimpse of Riddell House, the legendary family mansion built with a timber fortune. Trevor's bankrupt father has brought him here with a goal: for Trevor and his sister to dispatch Grandpa Samuel to a nursing home, sell the property, divide the profits, and live happily ever after. But as Trevor explores the house, he discovers a lingering spirit whose agenda is at odds with that plan.
