The series "Odyssey" has become a classic of science fiction. We are here in the genre "Cosmic Opera". AC Clarke gives us here a fairly successful sequel to the series of Odysseys. After 2001 and 2010, the monolith has done its work, Jupiter became Lucifer, a new sun expected to burn 1,000 years. Europe is a world forbidden to men, protecting the monolith and encouraging life that developed there. Man has settled on Ganymede and the era of interplanetary tourism begins. In this context, a strange mountain Europe arouses lust of some influential groups of the Earth.
