I had a love/hate relationship with this novel. I gleefully cringed through the opening sequence of brain surgery (sans operating room). I enjoyed the descriptions of the maniacally brilliant killer. I even enjoyed the mix of sci fi and fantasy with the horror theme. However, this one eventually lost my interest by bringing in far too many unimportant elements. DARK MATTER just never comes through with a punch. It delivers gore to the max and has a potentially fiendish villain, but it fizzles before it really gets to the point. I was, needless to say, quite disappointed.One of the cover reviews for this book describes it as "a character portrait of a copletely amoral serial killer to rival Thomas Harris's RED DRAGON..." Do yourself a favor: read RED DRAGON instead; it's beautifully written and amazingly chilling.
