In a society where unwanted and troublesome teens are salvaged for their body parts, Connor, Risa and Lev continue to fight against the system that would 'unwind' them. The morality of unwinding has finally been brought into question and a new law passed. However, it has become big business, and there are powerful political and corporate interests, not to mention the illegal 'Parts Pirates', that want to see it not only continue, but expand. And then there is Cam, a teen who does not exist. Made entirely out of parts from one hundred other 'unwinds', Cam is a 21st century Frankenstein - a rewound struggling to find a true identity and meaning, and a place in society. But when a sadistic bounty hunter who takes "trophies" from all the 'unwinds' he captures starts to pursue Connor, Lev and Risa, Cam finds his own fate inextricably bound with theirs.
