Have you read The Little Stranger by Sarah Waters?
Just shortlisted for the 2009 Man Booker Prize, it's a cross between two of my favorites, House at Riverton and The Thirteenth Tale. The Little Stranger started a bit slow, but soon I was caught in its grips, and I realized, that was the point. The story creeps slowly, luring the reader into a crumbling house and introducing an equally crumbling family. At the end, my unanswered questions drew me back to the beginning, and I tried to piece it together. Were my conclusions right? I won't spoil it here, but if anyone wants a good chat about it, let me know!
I'm not sure why I haven't read Sarah Waters before, but now I'm on a mission to catch up with her previous titles. Just started The Night Watch.
