Devonshire Mansion

Your family has recently moved into your estranged, and now deceased, grandfather's old mansion, since your father got fired from coaching high school football. Again. The house is old, the windows are thin, the floor creaks and there are definitely mice in the walls. But more importantly, your odd but endearing little sister, Thalia, has REALLY taken a liking to the place. She says she never wants to leave. Not even to go to school, which, being the little freak she is, she's always loved. Now there's a pentagon in the attic and Thalia keeps getting nose bleeds and talking about her new friends. She hasn't left the house in weeks. She hasn't met anyone new. It might be over for you and your family, twin.
