The shadow family

Edith met the shadow family when she was six and she would tell her parents about them of course they never saw them so they thought she had imaginary friends but after a while they started to worry about her. Since they would always see her going to the same mansion that looked abandoned and then talking to someone either outside or inside of the house so they decided to move. Until twelve years later Edith is eighteen and moved back to her old home...after a day of moving in she sees the old mansion Again and the memories come back to her so she decides to go over there and see if the shadow family is still there.
