Ghost is part of a street hacker airboard gang who lives to break rules. When they realize that their world - Saga - is being periodically invaded by strange human beings, they don't know what to do. That is, until they learn the complicated truth: Saga is not just their world. It is a sentient computer game, the replacement to Epic on New Earth, and it's addictive. The Dark Queen who controls Saga is trying to enslave both its people and the people of New Earth. And she'll succeed unless Ghost and her friends - and Erik, from Epic, and his friends - figure out what to do.
