In a future where humanity has been divided between the inhabitants of Earth, confined in gigantic underground cities called Cities, and the descendants of the space colonists, who live in harmony with robots, a murder shakes the delicate balance between both worlds. Detective Elijah Baley, an Earthman with prejudices against robots and spacials, is forced to collaborate with R. Daneel Olivaw, a humanoid robot, to solve the crime and prevent a war between Earth and the Outer Worlds. This science fiction novel, written by Isaac Asimov, explores themes such as xenophobia, technological progress, and the coexistence between humans and robots.
