Ghost story master Mary Downing Hahn unrolls the suspenseful, spine-chilling yarn of a girl imprisoned for more than a century, the terrifying events that put her there, and a friendship that crosses the boundary between past and present.

A family moves into an old, abandoned house. Jules's parents love the house, but Jules is frightened and feels a sense of foreboding. When she sees a pale face in an upstairs window, though, 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 is determined to make contact with the mysterious figure and help 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.
