When an angry spirit begins to leave cryptic messages on her computer and threatens those around her, Cora is forced to dig into the town's notorious past to uncover secrets that will free the bonds that tie her and the spirit. With the help of her husband and their friend, Frannie, Cora uses her skills as an amateur historian in a search that takes them into unexpected terrain including subterranean passages, an eerie graveyard, and shadowy paths in isolated forests where a sinister predator is awakened. As they battle unpredictable supernatural powers, the story takes a poignant turn: the spirit's life is revealed, and both women, a century apart, examine threads into the past and the future, their loss and longing linked across the generations.
