"A sea of pale frightened faces stared out the window of the train carriage. Fingers clawed at the glass. A moment later the train was gone." Fran's twin sister Carli has vanished. Everyone thinks she has run away. But they don't know what Fran knows. They don't know about the unscheduled train that passes through the derelict Batesford Station. And they don't know about all those frightened faces. Fran knows if she is ever to see her twin sister again, it is up to her. But how can she find the place this frightening train comes from? And will she ever make it back home?
