Hahn, Mary Downing The Girl in the Locked Room: A Ghost Story (1974913511)
Jules's family moves into an old abandoned house. Her parents love it, but she's frightened and feels a sense of foreboding. When she sees a pale face in an upstairs window, she can't stop wondering about the eerie presence on the top floor-in a room with a locked door. Could it be someone who lived in the house a century earlier? Her fear replaced by fascination, Jules becomes determined to make contact with the mysterious figure and to unlock the door. Past and present intersect as she and her ghostly friend discover-and change-the fate of the family who lived in the house all those many years ago.
