What a great idea to highlight the integral of four novels of this great saga of science fiction, but also two new have been the prelude to it. In addition, the short introductory text helps to get an idea about the genesis of the novel not only, but also masterful Kubrick film. My only negative is the fact of having integrated a prospective text in the cycle. But it is only a matter of positioning inside news, rather than the interest of this short analysis (personally, despite his date falling in 2019, I have detached from the rest of the work, ) even if it shows the limits of such an attempt prediction (although we are not yet at the end of the second decade of the XXI century, we approach the corner ...) In any event, Arthur C. Clark was a great Science Fiction and you will not be disappointed if you decide to dive into this work. Enjoy reading.
