It's like nothing anyone has ever seen before. Utopia is the brand-new frontier of theme parks, a fantastic collection of Worlds each so authentic it takes the average visitor's breath away. Teeming with cutting-edge holographic and robotic technology, it has captured the nation's imagination. But it has also attracted a group of ruthless criminals. After infiltrating the park and its computer systems, their leader -- calling himself John Doe -- sets the parameters: If their shocking demands are met, none of the visitors to the park that day will be harmed; if not, then all hell will rain down. Dr. Andrew Warne, the brilliant engineer who designed much of the park's robotics, suddenly finds himself in a role he never imagined -- trying to save the lives of thousands of innocent people... one of whom just happens to be his daughter.
