Incarceron by Catherine Fisher - free excerpt

I've just finished Incarceron and before I post my review I wanted to let you know that you can read an excerpt of it free here.

It took me a while to get into the book as it blends two stories - inside the prison and outside but once I got involved I was completely hooked. And can't wait for the sequel Sapphique.

Here's the blurb: Incarceron is a prison unlike any other: Its inmates live not only in cells, but also in metal forests, dilapidated cities, and unbounded wilderness. The prison has been sealed for centuries, and only one man, legend says, has ever escaped. Finn, a seventeen-year-old prisoner, can’t remember his childhood and believes he came from Outside. He’s determined to escape, even though most inmates don’t believe that Outside even exists. And then Finn finds a crystal key and through it, a girl named Claudia who claims to live Outside — her father is the Warden of Incarceron and she’s doomed to an arranged marriage. If she helps Finn escape, she will need his help in return. But they don’t realize that there is more to Incarceron than meets the eye. Escape will take their greatest courage and cost far more than they know. Because Incarceron is alive.
