Park Jimin Warren has spent his entire life surrounded by the supernatural. As the son of famous paranormal investigators Ed and Lorraine Warren, he knows that ghosts, curses, and demons are very real. Still, he tries to live an ordinary life—until a new student named Jeon Jungkook asks for help. Ever since his family moved into an old house on the edge of town, strange things have been happening. Doors open on their own, whispers echo through the halls, and Jungkook’s eight-year-old sister has become obsessed with a mysterious woman only she can see. When Jimin, Ed, and Lorraine begin investigating, they discover that the haunting is far more sinister than anyone imagined. As terror grips the Jeon family, Jimin and Jungkook find themselves growing closer, unaware that a centuries-old evil has already chosen its next victim. In a battle between faith and darkness, the next generation of the Warren family will face its most dangerous case yet.
