I've never done drugs, but this made me feel like I might be on them. It was mind-boggling, and not as in 'awe-some' but more like 'what was that?' The first part seemed to drag on. The last part of the book, when the action finally starts up was good but it didn't rescue the book. The dentist scene made me think I had missed that this was a fantasy and not a mystery. But, no, it is a mystery. I can't imagine anyone I know going to that dentist and not feeling like something was totally off about it.
The language was over the top. My students used to say that it was part of life and I would tell them that so is human waste but we didn't need to spend our days in the sewer. I chose not to hang out in the sewer so I won't be reading any more books by this author.
