Guardian, by Alex London, the sequel to Proxy.
"Guardian is a high velocity dystopian that surprises at every turn and smashes stereotypes as it goes. It's a wild ride - I bit my nails down to nubs watching Syd and Liam careen towards their destiny."--Emmy Laybourne, NY Times Bestselling Author of Monument 14
In a former life, Syd (Sydney) Carton was a proxy, a nonperson with a name selected from an old book, forced to repay his crushing debt by serving as the whipping boy for a spoiled, wealthy young patron. Now the old system of credits, debts, and tech has crashed, leaving a post-Revolution dystopian society where the sinister Advisory Council rules, young Purifiers maintain order, and cultist Machinists plot to revive the technology-rich past. In this bleak and broken world, Syd, now known as Yovel, has become the reluctant symbol of the Jubilee. His enigmatic bodyguard, Liam, can protect him from armed Machinists but is powerless against a horrific disease spreading through the population. First to fall victim are the Guardians, heavily bio-engineered enforcers of the old system. As the government refuses to seek a cure, the disease spreads to the old elite class and threatens to become a pandemic. Syd decides he must act to find the cure.
