Affinity by Sarah Waters

I enjoyed this book, though I found the ending completely surprising. It really examines the way that people related to each other and why people help each other. I found Margaret's family hideous, but I was left wondering whether her choices didn't contribute to her misery. I enjoyed the twist at the end, but if this book were a mystery, I would think the author had left a bit too much out for the reader to be able to make a fair conclusion.
