Knox was born into one of the City’s wealthiest families. A Patron, he has everything a boy could possibly want—the latest tech, the coolest clothes, and a Proxy to take all his punishments. When Knox breaks a vase, Syd is beaten. When Knox plays a practical joke, Syd is forced to haul rocks. And when Knox crashes a car, killing one of his friends, Syd is branded and sentenced to death.

Syd is a Proxy. His life is not his own.

Then again, neither is Knox’s. Knox and Syd have more in common than either would guess. So when Knox and Syd realize that the only way to beat the system is to save each other, they flee. Yet Knox’s father is no ordinary Patron, and Syd is no ordinary Proxy. The ensuing cross-country chase will uncover a secret society of rebels, test both boys’ resolve, and shine a blinding light onto a world of those who owe and those who pay. Some debts, it turns out, cannot be repaid.

The pulse-pounding sequel to Proxy! Inspired by The Whipping Boy and Feed, this adrenaline-fueled thriller will appeal to fans of The Hunger Games and Divergent.

In the new world led by the Rebooters, former Proxy Syd is the figurehead of the Revolution, beloved by some and hated by others. Liam, a seventeen-year-old Rebooter, is Syd’s bodyguard and must protect him with his life. But armed Machinists aren’t the only danger.

People are falling ill—their veins show through their skin, they find it hard to speak, and sores erupt all over their bodies. Guardians, the violent enforcers of the old system, are hit first, and the government does nothing to help. The old elites fall next, and in the face of an indifferent government, Syd decides it’s up to him to find a cure . . . and what he discovers leaves him stunned.
