The subject matter wasn't too dark for my tastes, the main character was pleasingly off-kilter (if inconsistently portrayed), and I'm willing to suspend all sorts of disbelief for the sake of story. Unfortunately, I just didn't find the story compelling as told. There was some potential, but largely unrealized. None of the characters seemed fully developed (and there were only a couple I had enough interest in to wish that they would be better developed). I felt no sense of place, and little tension. My curiosity was never piqued, so I really didn’t care who killed these people for most of the book.
