The Time of the GhostDiana Wynne Jones
fantasy, young adult
There's been an accident!
She doesn't know who she is, and doesn't know why she's invisibly floating through the buildings and grounds of a half-remembered boarding school. Then, to her horror, she encounters the ancient evil that four peculiar sisters have unwittingly woken – and learns she is their only hope against a deadly danger.
