Incarceron

Incarceron is a very big prison. It's not just cells, but there are towns, metal forests, jungles, and seas. The prison has been locked from the outside world for centuries, and only a person, according to the legend, ever got out from there.
Finn, the main roles in this book, is a seventeen years old prisoner. He didn't remember anything about his childhood. Moreover, he believed that he was from the outside world. He found a crystal key and communicate with outside world girl named Claudia, daughter of warden of Incarceron.
Finn wanted to get out from the prison and Claudia believed she could help. However, they didn't realize that Incarceron hide many mysteries. The effort to get out from the prison is impossible and life is at stake.

Finally, I finish reading this book. This book is written by Catherine Fisher. Overall I give this book 3 of 5. At the beginning, the story is a little complicated and a little hard to understand how the world and the story like. Finn and Claudia have a really different world. At the beginning they didn't even connect one to each other until the middle of the story, then you will finally realize the real goal. They split some clans of people but didn't tell readers how the clans looked like. Moreover, the story didn't tell us how the prison named Incarceron looked like.
