I really wanted to enjoy this one, but it fell flat. The narration was excellent, but that’s about the only thing that was good about it. The storyline was thin at best, and what was there was wholly unbelievable. Additionally, when it came to equipment such as breathing equipment and other tools, the author failed to do proper research resulting in a story that contains a number of errors. The language was also over the top. When there’s a point to the language and it fits with the story, that’s one thing, but this was cursing for the sake of cursing – it was really irritating and made it difficult to finish the book. ***This book was given to me for free at my request and I provided this voluntary review.***
