I read The Last Time They Met before I read The Weight of Water, absolutley loved it, but in it, it tells you that Billy dies, so when I came to read Weight of Water I knew that she was going to die. But if I had read them the other way round, I would have learned in Weight of Water that the magdalen poems were writted about a girl who died when she was 16.
Why did she do this, whichever way round you read the books each contains a spoiler for the other?
