Finished this book the other day! Overall, it was a good read and helped me through a dry spell of books recently while I hunt for other good dive books. Some minor things like how the characters seemed sort of shallow and under developed. I could never guess the protagonists age either, sometimes he seemed like a post college mentality then other times I felt like he was 16. I found it well written, if a bit simple but overall an easy, enjoyable read I would recommend to any diver or even non diver!
