I stayed up late to finish the second half of this, so I'd say it's pretty good. I thought the concept was interesting and especially enjoyed the latter half. The first half was mainly set up, which is understandable. Things really got rolling toward the end though. There were times when I was just plain shocked and appalled (in a good way I suppose). Some things felt a bit unlikely, but it all worked out in the long run. I'm looking forward to the next book in the series :). P.S. - The cover is beautiful. It's what initally convinced me to read the book ;p.
