I was really pumped to read this book, and while I enjoyed much of the story, I was a little bit underwhelmed. However, this was a good fantasy read and I do recommend it if you like fantasy.
So there are two stories in this book: the story of Finn and the story of Claudia. And both stories involve the prison - Incarceron.
Finn woke up in the prison and had no idea about how he got there or even who he was. He saw the name on his clothes; he ran into some people; and he began a strange, violent life in the prison. There's fighting, lying, and violence in the prison. Finn always had the weird feeling, though, that he was from Outside and that he hadn't always been in Incarceron. He has a tattoo on his arm, and when he finds a woman who knows something about it, he works to find out who he is and how he can get out of the prison.
Finn's path eventually crosses with the path of Claudia's. Claudia is the daughter of the Warden of Incarceron. She's grown up privileged, yet she's unhappy now because a marriage is being arranged for her that she does not want a part of. She's from the Outside, supposedly, but ends up wondering much when she encounters Finn somehow.
In this book you are reading about each character and wondering how Finn can ever get out or if that's even possible. It was a good read and did have some surprises, but it didn't leave me feeling like I felt after reading The Hunger Games or The Knife of Never Letting Go.
