Though I've followed Konrath's blog for about a year, Afraid is the first book by him that I've read. It didn't hurt that it was free. Anyway, Afraid is a story about a town under siege by a handful of augmented and utterly psychotic super-soldiers. The pace is fast, the characters are believable enough, and it held my attention. Caveat: The gore is over the top (if you don't like graphic descriptions of violence, just move on), and the death count is enormous. Suspend your disbelief (super-intelligent monkey, anyone?) and don't bother looking for a hidden message. Subtle, it ain't.
