Is Escape Possible?

Incarceron by Catherine Fisher
Why did I read it?
Its funny how I pick books sometimes. Basically, the sequel to Incarceron came out recently, showed up on my shelf and it sounded really interesting. But, I don't like to jump into the middle of the series, so I decided to read the first installment.
What happened?
Finn lives in Incarceron, a living prison that constantly watches, controls, and intimidates its inmates. As there is safety in numbers, Finn is part of a Scum band that raids other prisoners. But, Finn doesn't think of himself as a prisoner or as a member of the band. He has a special tattoo on his wrist and visions of "Outside." He assumes that he was born outside and cast into Incarceron, even though everyone thinks he's crazy. Armed with his visions and a Key, Finn seeks Escape.
Claudia is the daughter of the Warden of Incarceron. There are two things she knows; her father is the only man alive who knows the location of Incarceron, and she will be married to the heir to the throne, a long-held tradition. But, Claudia doesn't want to marry the current heir to the throne. He's an arrogant, self-righteous jerk and she can't stand him. Marrying the heir wasn't going to be too bad when it was Giles, but he mysteriously died several years earlier. Even though she is told it was an accident, she can't help but wonder if their is something darker going on at court.
What did I like or not like?
This is just a well-written book. The two complimenting storylines keeps things moving quickly, and the idea of a living prison is a scary and fascinating idea. I haven't quite finished the book yet, but I can't wait to see how it ends.
