This is a damn good vampire novel, but it's also a damn good police procedural. My husband's a cop and I'm a reporter, so I know the police beat pretty well. I can tell you Killough did a good job capturing the feeling of a small town police force, as well as the mechanics of cop politics in general.
From the standpoint of a vampire fan, I really enjoyed the portrayal of Garth and his struggles with his changed existance. In fact, I think Killough does the best job with that transformation I've ever read this side of Anne Rice. However, Garth is a much more admirable character than Rice's vampires, as human as he is superhuman.
Overall, finding a good vampire novel can be tricky, but Killough's book is so good I've read it a dozen times. And that says something, since the majority of vampire novels I buy I can't even finish because the writing style or characterization or plotting drives me nuts. But this book worked right down to the ground.
Do yourself a favor and buy it.
