This book is remarkable in that, in a genre in which almost everything has been done before, it is truly original. It tells the story of a race of dinosaurian creatures called Quintaglios, who have, in their recent history, formed a primitive civilization whose rules and regulations are sometimes at odds with the wild instincts they still retain.
The plot follows the fortunes of Afsan, a young astrologer who, through the use of a newly-developed instrument called the 'far-seer' (basically a telescope), comes to believe that what he has been told all his life regarding his world is untrue. The Quintaglios believe that the world is flat, and that the land floats down a never-ending river, watched over by 'the Face of God'. Afsan's research proves that the Face of God is actually a planet, and that their own world is one of its moons. What's more, their world orbits the Face of God so closely that there are tremendous pressures upon it - pressures which will one day tear it apart.
Afsan faces much resistance as he tries to convince his people of his theories and persuade them that they must find a way to escape their world before it's too late - their society is dominated by a religion which refuses to tolerate anything that undermines their beliefs (there are obvious parallels with our own society's history here). But Afsan also has his allies ...
I found this book so intriguing I was unable to put it down. The characters are well-drawn and, despite being members of a fictional species, completely believable. At times you can almost think of them as human, before something like an instinctive snarl at the invasion of one's territory reminds you that they are a primitive race still at war with their own natures as they struggle to be 'civilized'. This balance between culture and wildness in the Quintaglios makes fascinating reading, and I would thoroughly recommend this book to anyone with an interest in sci-fi and fantasy novels, alien empires, or dinosaurs.
