The world is falling apart, the System is crumbling, and Avery Cates is right where he belongs: in a maximum-security nightmare. After the chaos of the plague, Cates finds himself incarcerated in a high-tech hellhole designed to break the strongest wills. But even behind bars, he can't escape his reputation or the people who want to use his specific set of lethal skills.
When a daring escape opportunity presents itself, Avery realizes he’s just jumping out of the frying pan and into a global fire. Outside the prison walls, a new power vacuum has emerged, and rival warlords are fighting over the scraps of a dying civilization. Cates is forced to navigate a landscape of ruined cities and lawless wastes to track down a secret that could change the balance of power forever.
As his past sins continue to haunt him, Avery must decide if he’s a man seeking redemption or just a killer who is tired of running. In a world where the only law is survival, the "Eternal Prison" might be the one he carries inside his own head.
