Very good book. I won it today. I felt it. A medium book, with a very good final part. The encounter with the extremely agressive Zark (inspired in Darth Vader). The philosophical encounter with the fantastic pilot of the Vandervecken. And the final (long) encounter with Ciro. I remember looking into the eyes of Ciro. I felt very interesting he was not the normal kind of a scientist. Very interesting book.
