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. Thanks to their high-profile revolt at the Happy Jack Harvest Camp, people can no longer turn a blind eye to unwinding. Ridding society of so-called troublesome teens might be convenient, but its morality has finally been brought into question and a new law passed. However, unwinding 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.

Connor, Risa and Lev each struggle to rescue as many AWOL teens as possible and offer them sanctuary. But life at the Graveyard is hard, rivalries bubble under the surface and the cracks are beginning to show.

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...
