When an experiment with a new type of robot brain goes awry, the unthinkable happens and Caliban is created. A robot without guilt or conscience, a robot with no knowledge of or compassion for humanity--a robot without the Three Laws.

In a universe protected by the Three Laws of Robotics, humans are safe. The First Law states, A robot may not injure a human being, or, through inaction, allow a human being to come to harm. When an experiment with a new type of robot brain goes awry, the unthinkable happens. Caliban is created... A robot without guilt or conscience. A robot with no knowledge of or compassion for humanity. A robot without the Three Laws. Caliban is a searing examination of Asimov's Three Laws of Robotics, a challenge welcomed and sanctioned by Isaac Asimov, the late beloved genius of science fiction, and written with his cooperation by one of today's hottest talents, Roger MacBride Allen, New York Times bestselling author of Ambush at Corella, The Modular Man, and The Ring of Charon.

Among Asimov's contributions to science fiction are the 'Three Laws of Robotics', ethics built into every robot to ensure it never hurts humans. In 1990, Asimov developed the idea of a robot subject to revised laws - Caliban. This book follows the possible adventures of such a robot.

“Fast-paced action . . . first-rate sf space adventure” (Library Journal) from the #1 New York Times–bestselling author of Star Wars: Thrawn. Deep in space lies the black hole known as Angelmass, so called because it emits enigmatic particles with the unusual ability to render humans calm, reasonable, and incapable of lying—which would normally be seen as a good thing. But not by everyone. For while Empyrean human colonies on the edge of the galaxy utilize the power of the “angels,” the Earth-based Pax empire views the emissions as a threat that could be used to subvert humanity. Academic Jereko Kosta is pressed into service by the Pax to spy on the Empyrean, joining the crew of a ship actively hunting the particles. But what he learns turns out to be both scientifically fascinating and morally frightening. When the Pax make an aggressive move that may lead to all-out war with the Empyrean, Kosta is the only one who can stop the conflict between the human powers and force them to see that the angels they’re about to fight over are far from holy . . . Timothy Zahn combines provocative ethical questions with the same level of vivid sci-fi action that made his Star Wars: Thrawn a New York Times bestseller to deliver “a serious SF novel sneakily posing as an enormous golden-age thrill ride” (Locus).
