Clio Barnes learns of her estranged mother Alexandra’s death just after leaving a party in New York. Hungover and shaken the next morning, she travels to her childhood home in New Jersey, where she joins her sisters, Leda and Daphne.
The three share a strained history shaped by Alexandra’s erratic behavior, her supernatural beliefs, and her memoir, Demon of Edgewood Drive—a book the family silently agreed never to read. Their father, long divorced from Alexandra, keeps a cautious emotional distance from the subject of their former life.
When their aunt announces a funeral, the sisters refuse to attend, certain it will be filled with Alexandra’s odd friends and self-proclaimed mystics. Clio decides to go anyway and convinces Tommy, Leda’s husband, to accompany her.
At the elaborate Victorian home hosting the funeral gathering, Clio meets Alexandra’s partner Roy and an eccentric cast of spiritual devotees. There, she learns that her mother never sold the infamous house on Edgewood Drive—the supposed site of the demon Alexandra wrote about—and that she actually died inside it.
