Incarceron is a prison so vast that it contains not only cells and
corridors, but metal forests, dilapidated cities, and wilderness. It has
been sealed for centuries, and only one man has ever escaped. Finn has
always been a prisoner here. Although he has no memory of his childhood,
he is sure he came from Outside. His link to the Outside, his chance to
break free, is Claudia, the warden's daughter, herself determined to
escape an arranged marriage. They are up against impossible odds, but
one thing looms above all: Incarceron itself is alive . . .
