Incarceron

by Catherine Fisher

Finn is on the inside. Claudia is on the outside. Incarceron, the prison, keeps their two worlds from coming together.

The thing about Incarceron is: if you're on the inside, there's no getting out. No one knows where it is and no one knows exactly WHAT it is either. Only the Warden and the inmates know what really goes on inside the walls of Incarceron.
