I have to say that the marketing for this book seemed a bit unclear, and I wasn't sure going in if it were an Urban Fantasy or a "straight" mystery with a few supernatural elements. Either was fine since I like both of those (and since I was fairly sure it was *not* a Paranormal Romance). I suppose that the folks who bought the first four books were clear on what they were getting though.
Anyway, the answer to my question turned out to be "straight mystery with a few supernatural elements". Apart from the fact that Pepper can talk to ghosts, there are no other fantasy elements in the book -- It's implied that voodo dolls *might* work as wards, but that's never proved or disproved. (Though I suppose it's closer to disproved).
Anytime you have a first-person story, how much I enjoy the book is going to depend highly on how likeable (or at least compelling) the narrator is. After that, the plot has to carry the rest. Unfortunately, in this case, I didn't like Pepper, and I thought the plot was awful.
First, I thought Pepper was not very likeable. To start off with, she manipulated her boyfriend through sex and promises of sex and lied to him constantly. Second, her issues with prison seemed a totally artifical imposition to slightly slow down the plot resolution. Third, I never saw anything in her that could inspire the bunch of hard-cases she was saddled with, or that she had any organizational ability that would allow her to pull off a win on the reality show.
As for the plot, there were really two. An 'A' plot of solving a 20 year old murder and a 'B' plot that was sort of a Caddy Shack/Meatballs one of social outcasts competing with blue-bloods. The 'A' plot was in a word, stupid. It relied on an almost complete red-herring which nonetheless was forced to advance the search through sheer coincidence as far as I could tell, and a murderer who was only brought to justice because he was dumb-as-a-post about keeping incriminating evidence around for 20 years. The actual setup of the murder still seems completely implausible to me.
The 'B' plot strains credulity as well. Trying to imagine a local public-tv reality show that becomes wildly popular is hard in the first place. To imagine how Pepper could have been dragged into it with no foreknowledge and without signing umpteen releases is impossible. I also find it impossible to imagine attracting a bunch of local blue-bloods to such an affair on a prolonged basis, or that the whole thing wouldn't have been stopped after the murder of one of the participants. (Which apparently had no effect at all on the shooting, or envinced any discussion with the producers).
I'm sorry, but I just couldn't buy *any* of this book. I would give it one star, but the author can put words together into paragraphs which one-star authors can't..
