Who's behind the voice that wails at night? Who are the ghosts that lurk in the corner of the attic? These are the questions that puzzle Tegwen when she visits her father. What exactly happened there many years ago? The boundary between reality and the spirit world overlaps in this horror novel, the author's third novel in the Whap! series for teenagers.
