Query: Criminally boring

The biggest problem with this book isn't the graphic aberrant sex scenes, it's that Delany (who I firmly believe IS a good writer) is trying so hard to shock that it just comes off as boring. If you want to explore the pathology of the psychotic killer, read The Killer Inside Of Me. If you want to examine the psychology of bizarre sexuality, read the works of the Marquis de Sade or Anais Nin.
