Query: Riveting

This is a fabulous, riveting book that moves at a good clip. I am a slow reader if I am not inspired by what I am reading. This had me turning pages faster than I ever have and I finished it in recored time. My only slight criticism is the last 40 pages were a bit dull compared to the previous 540! It could have ended sooner and with more impact.
