There's been an accident!Something's wrong!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.
