I listened to this book in audio format, and it was so good. I thought that the narrator did a good job performing the piece and that the story itself was very well done. It kept me wanting to know more and each twist and turn shocked me. I was not expecting so many things to have happened, I only wish that they had been revealed to Nina. I thought that the ending was almost a cop out and that I could have been done better, but that overall I enjoyed the book a lot. So far John Marrs has had the audiobooks that I pay the most attention to.
