I didn't connect with this book, which is too bad, as I really wanted to like it (especially its setting, and the links with Poe's original story). But in the end, it didn't work for me. Mostly I found the characters bland and not really consistent in their behaviour.(show spoiler)
As for the love triangle, since I didn't find the characters enjoyable, I admit I didn't care for it either.
Another problem for me was that events tended to follow each other a little too abruptly to my taste. I had to read back several times, wondering how the characters ended up being there or doing that. I kept feeling that I was missing something—that some parts were missing.
On the other hand, the world depicted in this story is indeed appealing—all the glitter of a despaired society trying to drown into drugs, nice clothes and parties, because facing the grim truth outside would be even more depressing. There's something compelling in that.
