While this book starts out rather modern, it moves to something more of a supernatural and science fictiony setting that's closer to what you'd find in a comic book rather than a modern ghost story. The characters are okay, though the story gets muddled by not being very clear about who's doing what during action scenes.
It also seems that there are a lot of sex scenes in this book. While the sex scenes are okay, they don't add much particularly and I might say even take some from the overall rather good piece... even to the point where it feels like some sort of juvenile wish fulfillment.
For example, there's a scene where one of the ghosts communicates with a woman through a sex dream of sorts, even though he's perfectly capable of just materializing. He even makes his penis grow magically by three inches in the same scene... for no particular reason other than sexual gratification.
There are also elements of the story that are odd. For example, there are networked members of the community who help the ghost, but they randomly pop in and out or sometimes just show up once and are never mentioned again.
The ghosts also seem to work more like superheroes or some sort of grand intelligence rather than ghosts as we know them.
Use of colloquialisms and jargon is smooth, but the funny bit is how they mix Brits and African American characters, but don't feature nearly enough purely "good" Anglo-American or otherwise characters, though that might just be nit picking on my part.
On the whole I would recommend it.
Read it, it's definitely good enough, though don't believe it's going to be some sort of masterpiece, because it really isn't.
Kind of more like the script for a great comic book or HBO series or something similar and mostly just OKAY-ISH readingwise.
I love this book
