Books in the The Penrose series series

On a world of intelligent robots who seem to have forgotten their own distant past, it is a time of war as the soldiers of Artemis City set out to conquer everything within range on the continent of Shull, killing or converting every robot they capture to their philosophy, while viewing their own wire-based minds as nothing but metal to be used or recycled for the cause.Elsewhere, the more individualistic robots of Turing City believe they are something more than metal, but when the Artemisian robot Kavan sets out on a determined crusade to prove himself, even Turing City can't stand against him. Increasingly tied up with Kavan's destiny is Karel, a Turing robot with elements of Artemis's philosophy already woven into his mind ... as well as Karel's wife Susan, and their recently created child..Following the inevitable violence and destruction, Artemisian ambition focuses elsewhere and a journey begins towards the frozen kingdoms of the north ... and towards the truth about the legendary 'Book of Robots', a text which may finally explain the real history of this strange world ...In a completely alien but brilliantly realized landscape, here is a powerful story of superb action, barbaric cruelty and intense emotional impact.

Appointed Commander of the Emperor's Army of Sangrel, Wa-Ka-Mo-Do of Ko tries to establish relations between the existing robot population and the humans who have recently arrived on Yukawa. On the continent of Shull, Kavan forms the Uncertain Army and is marching to Artemis City. Upon discovery that the city's generals have made an alliance with the humans, he retreats to Stark where he plans the eventual overthrow of Artemis and the humans. Meanwhile, Karel is heading South, hoping to be reunited with Susan, his wife. As he walks, he hears more of the stories of the robots, and begins to understand something about his place on the world of Penrose. But with limited resources and tensions growing between robot and human it's only a matter of time before problems arise. And it's becoming more and more apparent that the humans are a lot more powerful than the robots first expected . . .
