The past isn't always dead or buried... When Joss Grant, adopted at birth, inherits Belheddon Hall – a beautiful old house on the East Anglian coast – it is like a dream come true. Eager to begin a new life there with Luke, her husband, and Tom, her small son, she is also impatient to find out about her newly discovered family who lived there for generations. But not long after they move in, Tom wakes screaming at night. Joss hears echoing voices and senses an invisible presence, watching her from the shadows. Are they spirits from the past? Or is she imagining them? As she learns, with mounting horror, of Belheddon's tragic and dramatic history, her fear grows very real, for she realises that both her family and her own sanity are at the mercy of a violent and powerful energy which seems beyond anyone's control.
