In this sequel to Proxy, we first see Syd as an assassination attempt is made on his life. In the new world, led by the Rebooters, Syd is the figurehead of the Revolution. Liam, an 18-year-old Rebooter, is Syd's bodyguard and must protect him with his life. But Machinists with guns aren't the only danger in the post-Jubilee world. People are falling ill-their veins show through their skin, they find it hard to speak, and sores erupt all over their bodies. Guardians are hit first, and the government does nothing to help. Syd decides it's up to him to find a cure...And what he discovers leaves him stunned: The only way to stop people from getting sick is to reverse the very revolution that he and Knox began.
