I've been meaning to check out the work of Guy N. Smith, in particular his Crabs series, for a very long time. Fortunately for me, David Zuzelo has written extensively about just those books and what's good about them. Check out his blog Tomb It May Concern and his posts Crustacean Domination parts one and two He promises a third post in the near future.
Here's a quick quote about the first book, Night of the Crabs, as well as Zuzelo's own banner:
Night Of The Crabs plays like a classic horror film of the 50's, with a good helping of 70's gritty gore slathered on top. The prose is tight and words are not wasted-each detail furthering the story towards gory conclusions. There is the tendency in Smith's world (and it is a fairly unified place to my experience) for people to act utterly illogical. But it doesn't feel that way as you read along, instead it feels as if the writing is in fast forward.
