It's been a few months now since XR_935 met Emma, a human girl who wasn't supposed to exist. Robots thought they'd eliminated all humans, but some have survived all these years. Now, robots and humans live side by side, and the world is so much better for it. They've formed a new society, living together as equals.

Even if XR doesn't always understand humans, it is impressed by their creativity and ingenuity--especially considering all the terrible things that robots did to humans all those years ago. But some humans are not so quick to forgive. A group known as the Machine Breakers has emerged. They won't stop until they've destroyed every robot on earth--and any human who stands in their way. Can XR and Emma stop them? Or could this be the end of the robots--and the world as they know it?
