I did not enjoy this book at all.
I regret having to pick it up, actually. It was that bad.
I guess the whole "Paris" setting did not appeal to me, nor did these "revenant" people. Sure, the idea was original and creative, but I thought that the book focused more on the girl's -- see, I even forgot her name; it was THAT bad -- romance, rather than the storyline. And I got half-way before I ended up dropping it.
Should I give this book a rating or not? I don't know. I'll leave it as a one star, but I doubt I'll be able to pick this book up again.
