I read this book through someone who loves YA, but I actually felt like this transcends the genre. Yes, it's a world like our own, only with magic. Yes, there's a human girl as the heroine. (Speaking of the heroine, I loved Karou, even after the first few pages.)Yes, she falls for a supernatural hero. But the strange lyricism of the prose, and the uniqueness of the world set it apart. Some of the sentences were just beautiful in their imagery. The supernatural world is so weird and mythic and the writing fits it perfectly.ETA: Apparently Universal bought the film right. I'm very nervous about that because I think that it would require a huge amount of CGI for one thing, and for another, the writing has such an atmosphere and I'm worried they won't be able to translate that to film.
