Ghost is part of an anarcho-punk airboard gang who live to break the rules. And there's a good reason - their world, Saga, has a strict class system enforced by high-tech electronics and a corrupt monarchy. Then Ghost and her gang learn the complicated truth. Saga isn't actually a place; it's a sentient computer game. The Dark Queen who rules Saga is trying to enslave the people of New Earth by making them Saga addicts. And she will succeed unless Ghost and her friends - and Erik, from Epic, and his friends - figure out how to stop her in time.
