The first book in a series, Incarceron by Catherine Fisher tells of a prison world ravaged by poverty and despair. It is separated; a dark world with great technology. Outside the prison, people live a life of luxury. Claudia, a girl from the outside world, and Finn, a boy from the prison, are the main characters in this story. They meet through a magical stone they find in their respective places. With it, Claudia discovers that Finn was originally from the outside world. Later, Claudia recognizes him as her previous betrothed. This motivates her to get Finn out of the prison. A complicated process, the book follows the hardships Claudia and Finn face for his escape.
This novel has a great premise and fine element of mystery. Unfortunately, there were several flaws present in the book. The characters, Claudia and Finn, did not develop over the course of the novel. Also, there were many instances in which the story lagged; the book could have been shortened a little bit. Otherwise, the story keeps you reading till the end in order to see what will happen. Even though there is a conclusion, there is a little bit of a cliff-hanger. There is a second book, called Sapphique, and I would recommend it for anybody who enjoyed the first one.
