Incarceron

"Imagine a living prison so vast that it contains corridors and forests, cities and seas. Imagine a prisoner with no memory, who is sure he came from Outside, even though the prison has been sealed for centuries and only one man, half real, half legend, has ever escaped.

Imagine a girl in a manor house in a society where time has been forbidden, where everyone is held in a seventeenth century world run by computers, doomed to an arranged marriage that appals her, tangled in an assassination plot she both dreads and desires.
One inside, one outside
But both imprisoned.
Imagine a war that has hollowed the moon, seven skullrings that contain souls, a flying ship and a wall at the world's end.
Imagine the unimaginable.
Imagine Incarceron." -- by Catherine Fisher

I read this book and I have to admit at first I wasn't sure if it would be a good read BUT even though I was uncertain of it, it kept me reading! The reason for that is because there are these two story lines of two different people and you have NO idea how they connect! It was a good read, but probably one that I'm not going to own.
