The only one who escaped... and the one who could destroy them all.
Incarceron, the living prison, has lost one of its inmates to the outside world: Finn's escaped, only to find that Outside is not at all what he expected. Used to the technologically advanced, if violently harsh, conditions of the prison, Finn is now forced to obey the rules of Protocol, which require all people to live without technology. To Finn, Outside is just a prison of another kind, especially when Claudia, the daughter of the prison's warden, declares Finn the lost heir to the throne. When another claimant emerges, both Finn's and Claudia's very lives hang on Finn convincing the Court of something that even he doesn't fully believe.
Meanwhile, Finn's oathbrother Keiro and his friend Attia are still trapped inside Incarceron. They are searching for a magical glove, which legend says Sapphique used to escape. To find it, they must battle the prison itself, because Incarceron wants the glove too.
