One of the greatest science fiction cycle begins with this novel. This contrasts Culture, a political system intergalactic, a very bloodthirsty empire linked to a subtle game that seems to govern all aspects of the company. The confrontation is not limited to a battle of two players, all details will be disclosed elsewhere in end of the book takes place on two sites, including a world where fire is part of the ecosystem. This story keeps us in suspense from beginning to end and, for my part, I therefore advise to discover this author and to discover in Culture. Good reading.
