I just finished reading Incarceron by Catherine Fisher. This is a young adult fantasy novel. The concept is very intriguing. A society in pursuit of perfection takes all the lower class people and criminals and placed them in a massive prison-world. It is a fast paced and interesting read. It takes a while to get used to all the terms associated with the fantasy world, but eventually it makes sense. Lots of interesting twists and turns as well. I look forward to book #2, Sapphique, that comes out in December.
