This was a book that kept my attention. I really enjoyed the storyline and the characters were interesting. The narrator did a very good job as well. However, there was a little too much talking amongst the police /FBI at times for my taste. And I expected more of a surprise at the end to be honest. I was also a little disappointed that part of the storyline was not wrapped up (in my opinion). Not a bad novel but the ending was not as good as the rest of the story.
