Adrienne "Max" Maxwell has everything she wants in life. Except sleep. Her fear of the night (Nyctophobia) stems from the brutal murder of her mother when she was ten. Strange things keep happening to Max. Objects in her home disappear and she finds unwashed dishes from a meal she doesn't remember eating. As these problems continue, she begins to doubt her mental stability. Her new neighbor and customer, research scientist Angus McLaren, quickly discovers Max's fears. He finds this strong, independent woman appealing and works to gain her trust, even as her mother's killer looms nearby. Stopping him from carrying out his depraved agenda will require all of Max's strength and that of her family of friends.
