I finished it on Sunday and I'm still not sure what I think of it. It's basically a bunch of stand alone chapters about really bizarre murders. They're linked by the fact that high school boy and girl who are very interested in death and highly amoral take an interest in the cases and don't exactly get involved, but they make efforts to get close to the murders. (There are a couple of exceptions.)
At first, I didn't particularly like it because the stories are very disturbing and it seemed as though the entire point was just to push the limits. As I got in, though, there was some minor character development and background (enough to cause me to have a different view of the characters at the very end than I did at the beginning), so it wasn't just "Plot? What plot?" violence.
If I were to recommend it, I would do it for the writing style. It's very misleading and, several times, one thing was implied, but at the very end, I found out something completely different had happened.
Basically, I'm still not sure. I'm switching off with Danielle for the manga for the book, so I'm interested in seeing how they did the manga and what she thinks of the novel. Honestly, I don't think that the manga will have the appeal of the novel, because the writer can't obfuscate the identity of a killer, for instance, with careful use of pronouns and implications. And, to me, that was the biggest draw for the novel.
Has anyone else read this? Or heard anything about it? I'd love to hear other thoughts.
