Finn is a Prisoner in Incarceron: a giant, self-contained prison, sealed 160 years previously, in which lives the descendants of criminals and a few of the Sapienti, a clan of intellectuals who volunteered to be incarcerated to guide and offer wisdom to the inmates. Incarceron is a nightmare: violent, cutthroat, low on resources, subject to periodic lockdowns, everything taking place under the red glare of Incarceron’s Eyes.
Meanwhile, Outside, Claudia is the daughter of the Warden of Incarceron. She is caught up in court intrigue and an arranged engagement to a rather unpleasant prince. They are trapped by Protocol that requires them to live as if it is an earlier (but frustratingly vague) Era.
Then Finn finds a strange crystal Key bearing the same symbol that is mysteriously tattooed on his wrist; separately, Claudia breaks into her father’s study and finds an identical key.
I found the pacing to be off. I figured out a major reveal very early, and then got a bit bored as the same hint was dropped over and over again. Towards the end I had the opposite problem: things moved a bit too fast and with too many abrupt shifts—yes, they can get out! no, they can’t! Yes, they can! Jerk me around too many times and I will stop caring. Guaranteed. Incarceron didn’t hit that point, but it was a close call.
The world is interesting, though Outside is a bit underdeveloped: I wanted to be able to picture what Outside looks like, with its Era clothing, buildings, and transportation; to understand how their advanced tech fit around the edges of Protocol and the Era, and how their advanced tech is maintained; and, as we’re dealing with an upper-class arranged marriage, what the society’s gender dynamic is like. None of these details are really there. Incarceron is better developed and more creative, with vastly different societies and appearance in different areas. Tidbits of folklore and history are given as epigraphs preceding each chapter, offering tantalizing glimpses into the of depth to the world. Hopefully, the sequel will smooth out some of this volume’s kinks and delve deeper into the world she’s created—inside and outside of Incarceron.
