Martin is a creative author. The story has a very modern, energetic feel to it. The pacing is good. He does a good job with the characters and their back-stories. It's a compelling plot to the end.
On the flip side, I noticed several errors that escaped the proofer. At the end of the story, I was left wishing he had developed certain aspects more or gone in a different direction with a couple plot paths. This is one book that could have been a hundred pages longer and still kept my interest.
