Foreigner: Book Three of the Quintaglio Ascension

In Far-Seer and Fossil Hunter, we met the Quintaglios, a race of intelligent dinosaurs from Earth and learned of the threat to their very existence. Now they must quickly advance from a culture equivalent to our Renaissance to the point where they can leave their planet.
While the Quintaglios rush to develop space travel, the discovery of a second species of intelligent dinosaur rocks their most fundamental beliefs. Meanwhile, blind Afsan -- the dinosaurian Galileo -- undergoes the newfangled treatment of psychoanalysis, throwing everything he thought he knew about his violent people into a startling new light.
