Isaac Asimov's Inferno

In a Universe protected by the Three Laws of Robotics, humans are safe. The Second Law states, a robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
When a key politician is murdered, suspicion falls on Caliban... the only robot without guilt or conscience, with no need to obey or to respect humanity... a robot without the Three Laws. But the stakes go deeper than one man's life. Caliban is challenging long-held ideas of a robot's place in society. Will he lead his New Law robots in a rebellion that threatens all humanity?
The sequel to the bestselling Caliban is a searing examination of Asimov's Three Laws of Robotics, a challenge welcomed and sanctioned by Isaac Asimov, the beloved late genius of science fiction, and written with his cooperation by one of today's hottest talents, Roger MacBride Allen, author of The Modular Man, The Ring of Charon, and Caliban.
