In the quiet neighborhood of Hollow's Edge, Brandon and Fiona Truett are murdered and a neighbor, Ruby Fletcher, is sent to prison on the testimony of her neighbors. While Ruby's in jail, the neighbors cannot sell their homes and are forced to stare at the Truett's empty house. Fourteen months later, Ruby's conviction is overturned and she returns to the house she shared with Harper Nash. Harper is terrified, and to make things worse, she begins receiving threatening notes. She realizes someone didn't tell the truth about the night of the murders and now Harper must learn who the real killer is before he or she strikes again.
