I wanted to give this book a lower score and even considered quitting it a time or two. I did neither. I didn't quit because how do you know it doesn't improve later on and I didn't give it a lower score because there were actually a few really entertaining parts to it.
It could have been a good story but the conversations between characters and the explanation of Mark's illness border on the simplistic and ludicrous. I don't think that if I were trying to convince my girlfriend that I was a werewolf that I would start discussing or lecturing on ancient far eastern mythology and how it carries over into the modern era! Hell, I thought I was back in school!
The beginning was ok and the ending pretty good. It was that middle section that sank it for me.
