This ghost story is set on the wild Atlantic coast of North Devon and told through the eyes of Jenny, a girl of nearly nineteen, whose recently deceased grandmother Mary has bequeathed her Windover, the cottage where she is staying with her father and his girlfriend during summer vacation.
Before long, Jenny is troubled by visions of two teenage girls and learns from a photograph taken in 1934 that these girls are her grandmother Mary and Mary's friend Cathy. As the days go by, Jenny finds herself drawn into tragic events that occurred nearly eighty years earlier.
