Toroca, a Quintaglio geologist, is under attack for his controversial new theory of evolution. But the origins of his people turn out to be more complex than even he imagined, for he soon discovers the wreckage of an ancient starship -- a relic of the aliens who transplanted Earth's dinosaurs to this solar system. Now Toroca must convince Emperor Dybo that evolution is true; otherwise, the territorial violence the Quintaglios inherited from their tyrannosaur ancestors will destroy the last survivors of Earth's prehistoric past.
This edition includes the first chapters of Foreigner, the third book in the Quintaglio Ascension.
