In December 1975, the Lutz family moved into their dream home, the same home where Ronald DeFeo had murdered his parents, brothers, and sisters just one year earlier. The psychic phenomena that followed created the most terrifying experience the Lutz family had ever encountered, forcing them to flee the house in 28 days, convinced that it was possessed by evil spirits.

Their fantastic story, never before disclosed in full detail, makes for an unforgettable book with all the shocks and gripping suspense of The Exorcist, The Omen or Rosemary's Baby, but with one vital difference...the story is true.
