Prelude to Foundation
Isaac Asimov
 The story takes place on Trantor during the reign of Emperor Cleon I. It starts with Hari's presentation of a paper at a mathematics convention detailing how practical use of psychohistory might theoretically be possible. The Emperor of the Galactic Empire learns of this and wants to use Hari for political gain. After an interview with Hari, however, Cleon concludes that Hari is of no use to the Empire. Hari then meets reporter Chetter Hummin, who convinces him that Cleon's first minister Eto Demerzel is attempting to capture him, and that it is therefore imperative for Hari to escape and to try to make psychohistory practical. Thus, Hari goes on his "Flight" and is introduced to Dors Venabili by Hummin. Hari and Dors narrowly evade capture at Streeling University, following which the pair move to Mycogen. Hari and Dors are welcomed to Mycogen by Sunmaster Fourteen, the leader of Mycogen. Determined to work out his psychohistory with the knowledge that the Mycogenians supposedly possess, Hari decides to speak to a Mycogenian alone about history. He manages this by convincing Raindrop Forty-three to show him the prized Mycogenian microfarms, a prized source of food for the aristocracy and Mycogenians alike. When Hari inquires about that the peculiar Mycogenian ways might be the product of religious belief, Raindrop Forty-three is offended and says that the Mycogenians have something better: History. Hari inquires into the source of Mycogenian history and Raindrop Forty-three reveals that it is encompassed in "The book". Hari asks for the book but Raindrop Forty-three accepts on the condition that Hari allows her to touch his hair; (hair being expressively forbidden in Mycogenian society). When Hari starts reading the book, he finds it disappointing except for the revealing of what the Mycogenians call their home planet, Aurora. Hari and Dors are almost killed when they try to find what they suspect is a robot in the Mycogenian "temple" until Hummin arrives in the nick of time to save them. The action then shifts to the Dahl sector, where Dors displays her amazing knife fighting skills. While in Dahl they meet a guttersnipe named Raych (whom Hari later adopts as his son), and Yugo Amaryl (who would become Hari's partner in developing psychohistory). Towards the end of the novel, Hari, Dors, and Raych are kidnapped by agents from Wye, a powerful sector situated at Trantor's south pole. The finale reveals that "Hummin" is actually Cleon's first minister Eto Demerzel, who we later learn is in fact the robot R. Daneel Olivaw. By the end of the novel, Hari suspects that Dors is a robot, too. This theme would later be picked up in Forward the Foundation.
