I have mixed feelings about this one. The pacing was a bit slow and I found myself skimming a few pages. It wasn't terrible, just okay. Just right down the middle.

I liked it for the most part. Interesting premise and executed fairly well. Just a few slow chapters here and there. Enjoyable weekend read.
