It's hard to say anything about this book without giving things away. It is really well written. The two main characters, while not at all likable, are utterly fascinating. I can't say it was a joy to read because it creeped me out and left me will a feeling of discomfort and ickyness. Despite that (or maybe because of it?) I loved every minute of this novel. When it ended I literally flipped through the remaining pages of the book desperately searching for just a little bit more.
