About the book: year / From the author An author's prequel based on the author's work of the same name, but not based on his book. More like a film based on this work. If you do it from a book, you’ll just copy everything almost exactly the same, and you won’t get your own. This will happen anyway, no matter how hard you try to change everything or a lot. The result will be a copy and plagiarism. And accordingly, there will be no authorship. I have no use for it. Therefore, I will only use the film itself based on this work. Like an artist, copying another artist’s painting and adding something of his own, trying to understand how the painting itself was created in the process of painting. Besides, not everything in the film is the same as in the book. And a lot of inaccuracies. Since the work is ancient, like the film itself. And this is the best option for me to feel the author himself and his work. Use your imagination in the descriptions and create your own text with added events of your own. And try to write much deeper than the author of the work himself. Although the dialogues will be similar. Not exactly the same, but similar. Therefore, I pointed to the real author of the idea and work. But you can try to create something of your own. In addition, this work in a new wrapper will be followed by other "AQUANAUTS". They no longer have anything in common with the first ones. Nothing at all to do with either the book or the movie. There is no need to judge authorship and rights too harshly. I just need this prequel before doing other work. With respect to the reader A.A. Kiselev.
