I forgot to mention what a great narrator Scott Brick is. He does dialogue particularly well, and is a master of creating mood.
The book has quite interesting plot, but it could be much better if not overused and misused "suspension points". They are used too often and in very irritating way - you know, that someone in the book knows something, and you as a reader are the only person, that don't know what it is :-). That not the type of suspension I expect. Luckily these suspension periods are quite short, but what is even worse - eventual explanations are too often nothing but disapointing.
This is not your typical Lincoln Child novel. The characters and storyline just aren't believable. I finished it only because I was hoping that it was going to get better. It didn't.
The only bright spot was the narration. Scott Brick is always a pleasure to listen to.
Watch the movie "the abyss" same as this book but the movie is good. Author seems to have taken most of the plot and story line and just used it in his book.
