Query: Not bad but the writing needs to be improved

Very creative but the writer could be more careful not to repeat the same or similar information again and again in dialogues or most paragraphs. Readers who liked this book, for advanced and more mature readings, please check out No.205 of Amazon.com 500, THE UNIVERSE BELOW-Discovering The Secrets of The Deep Sea, and most of Clive Cussler's deep sea adventures, such as NIGHT PROBE! and others
