Query: Sometimes Haunting, But Ultimately Lacks Direction

This writer is clearly going places, but he needs to reign himself in. This book consists of a menagerie of weird artificial creatures and punchy ideas, woven together with an emotionally engaging multi-perspectival narrative. In hindsight (I read it a few months ago), the ideas really got under my skin, but as a story it just doesn't hang together as well as I'd hoped. More than a couple of chapters are masterfully executed, but others are vague and unfleshed. The book runs out of page-turning gas about halfway through. I got the sense that the author did not know where he was going plot-wise, and just kind of let the story spin out of control. Still, if you are looking for an intellectual mutagen, this is very worthwhile.
