Somerset, 1989. Janey Lestrange arrives to stay for the summer at the grand old house of the Hunter family. But something is wrong behind the beautiful façades of Vanes. Janey's childhood friend, Kitty Hunter, her brother and their eccentric parents - once so welcoming - do not seem to want her there.
It is only as the night of an ancient and mysterious family ritual looms closer that Janey comes to realise they need her . . .

Decades later, the tragic events of that unforgettable summer still cast the darkest shadow. Can the truth about what happened that night ever be brought into the light?
