Controlled By The Pull Of Another
Far-Seer (Quintaglio Ascension Trilogy, volume 1)
By Robert J. Sawyer
Many science fiction writers (Canadians in particular, because Canada) are not especially outgoing and thus not inclined to actively promote themselves (one reason why I try do that for them.. With one noteworthy exception: a former Waterloo resident and past Edna-Staebler-Writer-in-Residence  named Robert J. Sawyer, who, if he ever suffered from this common debility, managed to overcome it. As a result, his online bio is sufficiently voluminous that I find myself paralyzed by choice. What, if anything, to quote? So I will just link to the ten-thousand-word Sawyer version. Enjoy!
1992’s Far-Seer is the first volume in Robert J. Sawyer’s Quintaglio Ascension Trilogy.
The dinosaurs may have perished on Earth, but their descendants live on, on the habitable moon of a distant gas giant . The intelligent carnosaurs known as Quintaglios have no inkling of their past. Indeed, their grasp of the present is shaky. As far as they are concerned, they live on a vast island floating down a vaster river. They do not know that their world is a sphere or that the body their religion worships is the greater world around which theirs orbits.
Apprentice astrologer Afsan will change all that.
