Arista once dreamed of a planet full of humans. Now it scares her to death.

After the disastrous events at the human colony, Arista's reality has been turned upside down and she finds herself in a world in which the machines never came to power, and, in fact, are outlawed.

Now she and Frees must try and navigate this strange, new universe without getting killed by some anti-artificial nutjob. The only question is: without a Quantum Gate, how do they get back?

After she breaks out of jail, Arista must use all her guile and knowhow to find a solution. But that means getting off the glittering jewel of Manhattan and into the real world.

And she and Frees aren't the only ones who are looking for a way back.
