Well, at first, I thought it was about two missing people in an exotic island community. Then I thought it was about WWI, and the way it changed everybody, forever. Then I thought it was a ghost story. But then it turned out to be about domestic violence, and the many ways in which women have been victimised over the centuries.

Sark sounds fascinating, though. It's set there, and I used to confuse it with the Scilly Isles, but actually, it's next to Guernsey.

I enjoyed this. It's set in 1933, but also in 1923, and it's about parents and children, and anger and disappointment, and frustration, and your past coming back to kick your arse.
