"Ghost Walk" contains all of Brian Keene's signature witty prose and dialogue, memorable everyman characters and breakneck pacing. But it does not have the depth or the true quality to match it up to his other works.
Ghost Walk has the feel of a book written on a whim, as if one of Keene's fans had requested a sequel to "Dark Hollow" and he decided to knock one out quickly while he was working on other things. The premise is barely enough to sustain a full novel, and indeed, the book is only 275 pages long, which means it is barely long enough to even be called a novel.
On the plus side, it does introduce us to more of Keene's Labyrinth mythos - although it's not much more than we'd seen already.
All in all, though, this is not Keene at his best. As I have already said, this is largely because of the impression I get that he didn't really have his heart fully in it from the beginning.
I'm hoping, then, that whatever else was occupying his attention was a lot better, and a lot more representative of his real talents.
