Meanwhile, in the ruins of New York City, Mathilda loses her brother, Nolan Perez, to the forces of the Tribe, a group of survivors led by Felix Morales — who is also controlled by Arayt Shah.
Out west at Cheyenne Mountain in Colorado are “freeborn” robots, freed from the control of Archos R-14 in “Robopocalypse” by the work of a genius in Japan and his creation. These liberated robots have set up their own community, and are soon targeted by the the Arayt Shah-run Tribe and Gray Horse Army for annihilation or assimilation.
It is up to Parez, Iron Cloud, Wallace and others to fight to save both humanity and the freeborn robots, and that’s easier said than done.
Wilson’s style is unusual for a novel. Each character tells his or her own story, in present tense, with introductory passages presented by Arayt Shah itself. This technique was used in similar fashion in “Robopocalypse,” to great effect.
