Foreigner
Robert J. Sawyer
 In the beginning of the novel, Afsan is accidentally run over by a chariot, causing severe crush injuries to his face. As Quintaglios can regenerate large amounts of tissue, Afsan heals, and in the process, his eyes, which were cut out by Yenalb in Far-Seer, also regenerate. However, Afsan does not regain his sight, despite having fully anatomically functional eyes. Believing suggestions that the issue may be psychological, he consults Mokleb, who has recently pioneered the new field of psychoanalysis. While this does not cause him to regain his sight, it does cure the chronic nightmares and insomnia he suffered after setting up the royal culling in Fossil Hunter. With the moon on which the Quintaglios live continuing its inward spiral towards the giant planet known as the "Face of God", the death of their world continues to put a forced acceleration of Quintaglio scientific advancement. Within the discovered Jijaki spacecraft, the Quintaglios accidentally trigger the formation of a tower of kiit – a blue nanotech material. Much to their astonishment, this tower extends all the way to the Lagrangian point above the moon's surface. Novato ventures upwards, making a monumental discovery: she discovers that there is a sort of surveillance camera system overlooking all of the worlds to which the "Watcher" (from Fossil Hunter) had the Jijaki transport life from Sol III (Earth). Staying to watch, she glimpses many life-forms, including red blob-like creatures, Quintaglios, and humans. She also notices that several cameras are returning black screens, unsettling her as to the possible meaning. Proceeding to explore the structure at the top of the tower, she accidentally opens an airlock, nearly killing her. While saved by the emergency systems, she realizes that the Quintaglio aviation advancements up to that point will not be sufficient to evacuate their moon, as there is no air in space on which winged aircraft can fly. Meanwhile, Toroca makes an equally astounding discovery – another sentient species of saurian, inhabiting a small archipelago on the other side of the moon from the continent known as Land. These dinosaurs are markedly different both in physiology and psychology to the Quintaglios; most significantly, they use tools and cook meat, are capable of lying, and have a reduced sexual dimorphism, the last of which causes all Quintaglios except for Toroca – who has no territorial instincts – to immediately enter dagamant. After Captain Keenir kills two of the "Others" in such a frenzy, Toroca attempts to negotiate, not altogether unsuccessfully. However, the Others eventually decide that the Quintaglios are a threat to their survival and decide to exterminate them, sending a huge fleet for Land. In a last-ditch attempt to settle the dispute, Afsan ventures to one of the ships, where he is shot. Overcoming their cultural aversion to tools, the Quintaglios retaliate, using their prototype aircraft as bomber planes, dropping a napalm-like substance on the enemy fleet, destroying it. Afsan does eventually regain his sight, but shortly thereafter dies from his wounds. Toroca, having rescued a child of the Others, raises it as his own. In an epilogue, the Quintaglios have successfully achieved spaceflight, and send a great many starships out to many planets, including at least one – the Dasheter – to Earth, the original homeworld. Other advancements have been made as well; for example, the Dasheter is navigated by an AI named Afsan, built to mimic the mannerisms of the long-dead astronomer.
