It's the most advanced computer role-playing game ever: When you play you're really there--in a dark dream teeming with evil creatures, danger-filled fortresses, and malevolent sorceries.
The game plugs directly into your brain--no keyboard, no modem, no monitor. And for game hacker Arvin Rizalli and his friends, no cash up front, no questions asked . . . and no hope of rescue when the game goes horribly, deathly wrong.
