Inspired by the true-life story of Maggie Schilling. Maggie's disappearance and death in 1979 from the Ridges Asylum in Athens Ohio remains enshrouded in mystery to this day. Maggie's body was found nearly a month after her disappearance in the attic of the asylum in January of 1979 leaving behind a permanent stain. No one has been able to remove the stain. The haunted asylum is the story of Maggie Schilling re-imagined. 15-year-old Olivia and her family recently move from Connecticut into a home adjacent to the abandoned Lunatic Asylum. On her first night Olivia is haunted by the sight of Maggie in the attic window of the asylum. Maggie writes a message on the window of the asylum attic every night there is a full moon and then runs away from a dark figure in the room. Along with her twelve-year-old sister Sofia and the son of the Asylum caretaker named Logan they try and solve the mystery of Maggie Schilling's death. Why are the grave markers in the enormous asylum cemetery all numbered without no names? What is in the gravestone labeled Specimen? The three teens are desperate to solve Maggie's death and stir up enemies both living and dead.
