Two young girls. One hot, long, sultry summer.
And a rambling old English manor house where nothing is as it seems.

A successful London barrister, Catherine Christophe, goes missing the day before her wedding anniversary. The clue to her disappearance, it seems, lies buried thirty years in the past. 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 facades 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?
