'I'm all right. I'm Here. I'm me. If I wasn't, I wouldn't even be frightened. I wouldn't know. But something has happened to me. I can't see myself at all, no even a smear of shadow on the road. There's been an accident.
STOP THAT'
The ghost turns up one summer day, alone in a world she once knew, among people who were once her family. She knows she is one of four sisters, but which one? She can be sure of only one thing - that there's been an accident.
As she struggles to find her identity, she becomes aware of a malevolent force stirring around her. Something terrible is about to happen. One of the sisters will die - unless the ghost can use the future to reshape the past. But how can she warn them when they don't even know she exists?
